Map applies a function to each item in a list and returns a new list. Reduce applies a computation via a function to a list and returns a single result. Filter applies a condition to an iterator and returns a new iterator containing items that match the criteria. Together, map, filter and reduce allow programmers to write shorter Python programs without using loops.
This slide contains short introduction to different elements of functional programming along with some specific techniques with which we use functional programming in Swift.
This document provides an overview of functional programming with Haskell. It discusses key concepts of functional programming like immutable data structures and pure functions. It introduces Haskell types including basic types, tuples, lists, data types, and type classes. It covers Haskell functions like pattern matching, guards, and higher order functions. It also discusses Haskell concepts like laziness, currying, and polymorphism. Finally, it provides an introduction to monads in Haskell and discusses Haskell tools, frameworks, and performance.
This document discusses functional programming concepts like map, reduce, and filter and provides Swift code examples for applying these concepts. It begins with an introduction to functional programming and key concepts. It then covers Swift basics like function types and passing functions. The bulk of the document explains and demonstrates map, reduce, filter and their uses on arrays and optionals in Swift.

This document discusses reasoning about laziness in Haskell. It explains that functions and data constructors don't evaluate their arguments until needed. This laziness allows separating producers and consumers efficiently. However, laziness can also cause problems like space leaks from unevaluated thunks. The document demonstrates techniques like using seq, bang patterns and strict data types to control evaluation order and avoid space leaks. It also discusses how to determine which arguments a function evaluates strictly.

Haskell is a statically typed, non strict, pure functional programming language. It is often talked and blogged about, but rarely used commercially. This talk starts with a brief overview of the language, then explains how Haskell is evaluated and how it deals with non-determinism and side effects using only pure functions. The suitability of Haskell for real world data science is then discussed, along with some examples of its users, a small Haskell-powered visualization, and an overview of useful packages for data science. Finally, Accelerate is introduced, an embedded DSL for array computations on the GPU, and an ongoing attempt to use it as the basis for a deep learning package.
Beginning Haskell, Dive In, Its Not That Scary!priort
Haskell can get a bit of a reputation for being this lofty, academic, difficult to learn language. This talk aims to dispel this myth and offer an introduction to this beautiful and pragmatic language. From the point of view of someone who has been functional programming in Scala and Clojure for a while now, but who has, more recently been taking a dive into Haskell, this talk will give a basic introduction to Haskell. Hopefully it will encourage anyone who hasn't tried functional programming in Haskell to dive in too and give it a go.
The talk will be a whistle stop tour of some functional programming fundamentals in Haskell from basic data structures, logic constructs, functional transformations, recursion to some of the basics of Haskell's type system with data declarations and type classes.
This document provides a 3-sentence summary of the given document:
The document is a tutorial introduction to high-performance Haskell that covers topics like lazy evaluation, reasoning about space usage, benchmarking, profiling, and making Haskell code run faster. It explains concepts like laziness, thunks, and strictness and shows how to define tail-recursive functions, use foldl' for a strict left fold, and force evaluation of data constructor arguments to avoid space leaks. The goal is to help programmers optimize Haskell code and make efficient use of multiple processor cores.
Functional Programming - Past, Present and FuturePushkar Kulkarni
Functional programming has evolved significantly since its origins in lambda calculus. Key developments include Lisp (1958), ML (1973), Haskell (1990), and more recently languages for the JVM like Scala (2004) and Clojure (2007). Functional concepts like immutable data, higher-order functions, lazy evaluation and currying allow a more declarative style and improved performance. Advances like tail call optimization and parallelism address early performance issues. Future areas include dependent types as in Idris and embracing functional principles in mainstream languages like Java 8. Functional programming changes how we think about solving problems.
The document discusses how to rewrite Java code in Scala by taking advantage of Scala's functional programming features like case classes, pattern matching, filters, maps, folds, and generators to make the code more concise and readable. It provides examples of rewriting common Java constructs like filtering lists, mapping over lists, and reducing lists using these Scala features.
The document discusses different data structures for implementing dictionaries, including arrays, linked lists, hash tables, binary trees, and B-trees. It focuses on hashing as a technique for implementing dictionaries. Hashing maps keys to table slots using a hash function to achieve fast average-case search, insertion, and deletion times of O(1). Collisions are resolved using chaining, where each slot contains a linked list. The load factor affects performance, with lower load factors resulting in faster operations.
The Functional Programming Triad of Folding, Scanning and Iteration - a first...Philip Schwarz
The document discusses implementing various functional programming concepts like folding, scanning, and iteration to solve problems involving converting between digit sequences and integers. It provides examples in Scala and Haskell of using fold left to implement a digits-to-integer function and the iterate function to implement an integer-to-digits function. It also discusses using techniques like pipes in Scala and the $ operator in Haskell to improve readability by ordering function applications in the sequence they will be executed.
The document discusses Python's built-in functions for functional programming: map(), filter(), reduce(), and lambda. It provides examples of using each function to transform sequences. Map applies a function to each item in a sequence. Filter filters items based on a function that tests each item. Reduce combines items via a function to produce a single value. These functions allow functional-style programming in Python.
Functional programming is a programming paradigm that uses functions and avoids side effects, mutable data, and state changes. It is based on lambda calculus. Popular functional programming concepts include map, reduce, filter, take, drop, head, and tail. Functional programming languages like Haskell, ML, Scala, Clojure, and F# are used by companies like Twitter, Facebook, and Apache for applications involving big data processing.
Describes Map data structure, its methods and implementation using Hash tables & linked list along with their running time. Hash table components, bucket Array and hash function. Collision handing strategies: Separate chaining, Linear probing, quadratic probing, double hashing.
Ordered Maps and corresponding binary search
This document provides an overview of different data structures and sorting algorithms. It begins with an introduction to data structures and describes linear data structures like arrays, stacks, queues, and linked lists as well as non-linear data structures like trees and graphs. It then provides more detailed descriptions of stacks, queues, linked lists, and common sorting algorithms like selection sort and bubble sort.
The document discusses the C++ Standard Template Library priority queue, which provides constant-time access to the largest or smallest element while maintaining the heap property. A priority queue is a container adaptor that uses a heap to provide efficient insertion and extraction, allowing O(1) retrieval of the maximum or minimum element through top() and removal of the top element using pop(). It can be configured as a max or min heap using different comparators.

This document summarizes techniques for hashing, including hash functions, open addressing, linear probing, and double hashing. It discusses choosing good hash functions that distribute keys uniformly. For open addressing, it describes linear probing, which probes successive table locations when collisions occur, and double hashing, which uses two hash functions to determine probe positions. Analysis shows the expected number of probes is related to the load factor for these probing techniques.

A brief introduction to functional programming.
Even if slides present some simple Python code, functional programming patterns applies to other languages too.
(video of these slides available here http://fsharpforfunandprofit.com/fppatterns/)
In object-oriented development, we are all familiar with design patterns such as the Strategy pattern and Decorator pattern, and design principles such as SOLID.
The functional programming community has design patterns and principles as well.
This talk will provide an overview of some of these, and present some demonstrations of FP design in practice.
An Introduction to Functional Programming using HaskellMichel Rijnders
The document provides an introduction to functional programming using Haskell. It discusses Haskell's main features such as being purely functional, lazy, strongly typed, and supporting higher-order functions. It also covers Haskell's history, types, functions, pattern matching, and common data structures like lists. Programming techniques like recursion, algebraic data types, and type classes are explained. Examples of list processing functions and higher-order functions are provided.
An introduction to the basic concepts on functional programming, explaining why it is a hot topic for some years now, what it is and some suggestions of functional languages to be learned.
Java/Scala Lab: Анатолий Кметюк - Scala SubScript: Алгебра для реактивного пр...GeeksLab Odessa
SubScript - это расширение языка Scala, добавляющее поддержку конструкций и синтаксиса аглебры общающихся процессов (Algebra of Communicating Processes, ACP). SubScript является перспективным расширением, применимым как для разработки высоконагруженных параллельных систем, так и для простых персональных приложений.
Here is a recursive function to check if a list contains an element:
(defun contains (element list)
(cond ((null list) nil)
((equal element (car list)) t)
(t (contains element (cdr list)))))
To check the guest list:
(contains 'robocop guest-list)
This function:
1. Base case: If list is empty, element is not contained - return nil
2. Check if element equals car of list - if so, return t
3. Otherwise, recursively call contains on element and cdr of list
So it will recursively traverse the list until it finds a match or reaches empty list.
The Fuss about || Haskell | Scala | F# ||Ashwin Rao
The document discusses functional programming languages Haskell, Scala, and F# and their advantages over imperative programming. It notes they encourage a different problem-solving approach using concepts like immutable values, recursion, and avoiding side effects. Specific features highlighted include static typing with type inference, algebraic data types, pattern matching, and monads for controlling program flow and errors in a functional way. Examples show equivalent algorithms in different languages to demonstrate these concepts.
The document discusses functions in C programming. It begins by explaining what functions are and why they are useful. Functions help modularize programs, avoid code repetition, and allow for software reusability. Key benefits of using functions include divide and conquer programming and abstraction. The document then provides examples of function definitions, prototypes, parameters, return values, and scope. It also discusses calling functions, libraries, recursion, and other concepts related to functions in C.
The document discusses 5 programming languages that the author has learned over the years: Ruby, Erlang, Haskell, Common Lisp, and Clojure. For each language, it provides a brief overview of its origins, paradigms, and interesting features. It encourages readers to try the languages if they are interested in functional programming, parallelism, strong typing, metaprogramming, or Lisp dialects on the JVM.
Monads and Monoids: from daily java to Big Data analytics in Scala
Finally, after two decades of evolution, Java 8 made a step towards functional programming. What can Java learn from other mature functional languages? How to leverage obscure mathematical abstractions such as Monad or Monoid in practice? Usually people find it scary and difficult to understand. Oleksiy will explain these concepts in simple words to give a feeling of powerful tool applicable in many domains, from daily Java and Scala routines to Big Data analytics with Storm or Hadoop.
This document discusses first-class functions and lambda calculus. It begins with an overview of Alonzo Church and the origins of lambda calculus. It then covers first-class functions in JavaScript, functions as objects in Java, and first-class functions in Scala. The document also discusses generic higher-order functions and control abstraction.
Forget everything you know about Template Haskell. We will enter the beautiful world of Typed Template Haskell where its only possible to construct well-scoped and well-typed terms. Why? By writing our program in multiple stages, we can guarantee to eliminate the interpretative overhead caused by abstraction.
Matthew will give an introduction to Typed Template Haskell and then describe some examples of how to construct abstract and efficient programs using techniques from multi-stage programming. We will construct an "efficient" power function and also give a sketch of how to implement a SQL query compiler as inspired by the functional pearl "A SQL to C Compiler in 500 Lines of Code".
Matthew is a PhD student at the University of Bristol focusing on program generation with applications to optimisation. In the quest to write the perfect program he has become a regular contributor to GHC where he has recently been working on making the compiler easier to extend by using source plugins.
A Haskell module is a collection of related functions, types and typeclasses. Modules allow organizing code into namespaces and provide a way to selectively import functionality from other modules. Some key points about modules include:
- Modules manage types and functions into namespaces
- The main module can load other modules
- Modules are imported at the top of a file using import statements
- Functions and types can be selectively imported from a module
- Modules in the same parent folder can be in the same namespace
This document discusses monads in functional programming. It provides examples of optionals, arrays, and functions in Swift that exhibit monadic properties. It then defines monads more formally and describes some common monad types like the writer, reader, and IO monads. It shows how monads allow encapsulating effects like logging or environment variables while preserving referential transparency. The document concludes by discussing potential applications of monads to mobile apps.
Programs are composed from a series of computation steps. Standardizing those steps and how they are chained simplifies both the development and maintenance of applications.
Monads are the abstractions that help do just that. Functions are all one needs a computation building blocks, as they can be lifted to abstractions that hide complexity.
This document provides an introduction to the Python programming language. It covers Python's background, syntax, types, operators, control flow, functions, classes, tools, and IDEs. Key points include that Python is a multi-purpose, object-oriented language that is interpreted, strongly and dynamically typed. It focuses on readability and has a huge library of modules. Popular Python IDEs include Emacs, Vim, Komodo, PyCharm, and Eclipse.
This document discusses various Yin-Yang concepts in software development, including:
- Effort and knowledge, theory and practice, design for manufacturing and design for assembly represent opposing yet interconnected concepts.
- Programs (E-programs) built on simpler programs (S-programs) balance ease of use and performance.
- Designing for both short-term efficiency and long-term evolvability requires balancing opposing priorities.
- Many software development processes involve balancing logical thinking with creative control, and reducing complexity through modularity.
How to start functional programming (in Scala): Day1Taisuke Oe
Functional programming involves composing computations like functions in a modular way. Scala supports both functional and object-oriented paradigms. Functions in Scala can be composed through methods like andThen and compose. Higher order functions allow functions to take other functions as arguments or return values. Pure functions always return the same output for the same inputs and avoid side effects. The Monoid typeclass abstracts the concepts of combining elements of a type and providing a default value, allowing new folding behaviors to be defined for types through implicit values. This allows behaviors to be extended to existing types without modifying them.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

2. Why FP?
• Source of new ideas
• Expressiveness
• Multi-core CPUs
• Different paradigm
New ideas:
Garbage collection (LISP)
Type inference (simply
typed lambda calculus)
Generics
Type classes
Expressiveness:
DSLs
3. What is it?
• Different programming paradigm
• OO
• Logic
• Procedural
• Functions are the main element in the
language
4. Function applications
“Functional programming is so called because a
program consists entirely of functions. [...]
Typically the main function is defined in terms of other
functions, which in turn are defined in terms of still
more functions, until at the bottom level the functions
are language primitives.”
John Hughes, 1989 -Why functional programming matters
7. Lambda Calculus (I)
• true = λxy. x
• false = λxy. y
• NOT a = (a)(false)(true)
• a AND b = (a)(b)(false)
• a OR b = (a)(true)(b)
• a XOR b = (a)((b)(false)(true))(b)
8. Haskell
• Academic origin
• Named in honor of Haskell Curry
• Defined by a committee
• First version released on 98 (Haskell 98)
9. Features
• Pureness
• Type Inference
• Algebraic datatypes (ADTs)
• Pattern Matching
• Lazyness
• High Order Functions
• Currification (aka Partial Application)
• Type Classes
• Monads
10. Pureness
• No side-effects
• A function call can have no effect other
than to compute its result
• Expressions can be evaluated at any time
• Programs are “referentially transparent”
Good for:
* reasoning
* compiler optimization
* concurrency
11. Type Inference
Let’s see the types for these declarations:
four = 4
add x y = x + y
emphasize x = x ++ “!”
12. Algebraic datatypes
Enumeration:
data Season = Summer | Winter | Autumn | Spring
Product:
data Pair = Pair Int Int
Sum:
data Shape = Circle Float | Rect Float Float
Polymorfic & Recursive:
data Tree a = Leaf a | Node (Tree a) (Tree a)
22. Type Classes
• Created to solve the problem with numeric
operator overload and equality testing
• Some type classes defined by Haskell 98:
• Eq
• Read/Show
23. Type Classes (I)
class Eq a where
(==), (/=) :: a -> a -> Bool
x == y = not (x /= y)
x /= y = not (x == y) You can define what is
called a “minimal
implementation”.
24. Type Classes (II)
data User = User { name :: String }
instance Eq User where
user1 == user2 = name user1 == name user2
instance Show User where
show user = name user
25. Automatic Derivation
data Season = Summer | Winter | Autumn | Spring
deriving (Show, Eq)
show Summer
> “Summer”
Summer /=Winter
> True
26. Monads
• Adds to the type system a way to describe
actions
• The actions will happen in a certain order
28. Monads
thing1 >>= x ->
func1 x >>= y ->
thing2 >>= _ ->
func2 y >>= z ->
return z
do
x <- thing1
y <- func1 x
thing2
z <- func2 y
return z
sugar no-sugar
29. Monads
class Monad m where
(>>=) :: m a -> (a -> m b) -> m b
(>>) :: m a -> m b -> m b
return :: a -> m a
“return” is a bad name, it
actually injects a value
into the monadic type.
30. Logger Monad
type Log = [String]
data Logger resultType = Logger (resultType, Log)
deriving Show
record x = Logger ((), [x])
instance Monad Logger where
return value = Logger (value, [])
prevLogger >>= nextAction =
let Logger (prevResult, prevLog) = prevLogger
Logger (newResult, newLog) = nextAction prevResult
in Logger (newResult, prevLog ++ newLog)
