What is Heuristics?
A heuristic is a technique that is used to solve a problem faster than the classic methods. These techniques are used to find the approximate solution of a problem when classical methods do not. Heuristics are said to be the problem-solving techniques that result in practical and quick solutions.
Heuristics are strategies that are derived from past experience with similar problems. Heuristics use practical methods and shortcuts used to produce the solutions that may or may not be optimal, but those solutions are sufficient in a given limited timeframe.
History
Psychologists Daniel Kahneman and Amos Tversky have developed the study of Heuristics in human decision-making in the 1970s and 1980s. However, this concept was first introduced by the Nobel Laureate Herbert A. Simon, whose primary object of research was problem-solving.
Why do we need heuristics?
Heuristics are used in situations in which there is the requirement of a short-term solution. On facing complex situations with limited resources and time, Heuristics can help the companies to make quick decisions by shortcuts and approximated calculations. Most of the heuristic methods involve mental shortcuts to make decisions on past experiences.
Heuristic techniques
The heuristic method might not always provide us the finest solution, but it is assured that it helps us find a good solution in a reasonable time.
Based on context, there can be different heuristic methods that correlate with the problem's scope. The most common heuristic methods are - trial and error, guesswork, the process of elimination, historical data analysis. These methods involve simply available information that is not particular to the problem but is most appropriate. They can include representative, affect, and availability heuristics.
We can perform the Heuristic techniques into two categories:
Direct Heuristic Search techniques in AI
It includes Blind Search, Uninformed Search, and Blind control strategy. These search techniques are not always possible as they require much memory and time. These techniques search the complete space for a solution and use the arbitrary ordering of operations.
The examples of Direct Heuristic search techniques include Breadth-First Search (BFS) and Depth First Search (DFS).
Weak Heuristic Search techniques in AI
It includes Informed Search, Heuristic Search, and Heuristic control strategy. These techniques are helpful when they are applied properly to the right types of tasks. They usually require domain-specific information.
The examples of Weak Heuristic search techniques include Best First Search (BFS) and A*.

An algorithm is a set of steps of operations to solve a problem performing calculation, data processing, and automated reasoning tasks.
An algorithm is an efficient method that can be expressed within finite amount of Time and space.
The important aspects of algorithm design include creating an efficient algorithm to solve a problem in an efficient way using minimum time and space.
To solve a problem, different approaches can be followed. Some of them can be efficient with respect to time consumption, whereas other approaches may be memory efficient. To Evaluate An Algorithm we have to Satisfy the following Criteria:
INPUT: The Algorithm should be given zero or more input.
OUTPUT: At least one quantity is produced. For each input the algorithm produced value from specific task.
DEFINITENESS: Each instruction is clear and unambiguous.
FINITENESS: If we trace out the instructions of an algorithm, then for all cases, the algorithm terminates after a finite number of steps.
EFFECTIVENESS: Every instruction must very basic so that it can be carried out, in principle, by a person using only pencil & paper.Algorithm : Systematic logical approach which is a well-defined, step-by-step procedure that allows a computer to solve a problem.
Pseudocode : It is a simpler version of a programming code in plain English which uses short phrases to write code for a program before it is implemented in a specific programming language.
Program : It is exact code written for problem following all the rules of the programming language.Algorithm can be described (Represent) in four ways.
Natural language like English:
When this way is chooses, care should be taken, we
should ensure that each & every statement is definite.
(no ambiguity)
2. Graphic representation called flowchart:
This method will work well when the algorithm is small& simple.
3. Pseudo-code Method:
In this method, we should typically describe algorithms as
program, which resembles language like Pascal & Algol
(Algorithmic Language).
4.Programming Language:
we have to use programming language to write algorithms like
C, C++,JAVA etc.Comments begin with // and continue until the end of line.

Lecture Note-2: Performance analysis of AlgorithmsRajesh K Shukla
The execution of an algorithm requires various resources of the computer system to complete the task. The
performance of algorithms depends on the use of these resources. The important resources which contribute
to the efficiency of the algorithms are the memory space and the time required for successful execution of
algorithm. The efficiency of an algorithm is measured in terms of the time and the space required for its
execution therefore analysis of algorithms is divided into two categories
An algorithm is a tool for solving any computational problem. It may be defined as a sequence of finite,
precise and unambiguous instructions which are applied either to perform a computation or to solve a
computational problem. These instructions are applied on some raw data called the input, and the
solution of the problem produced is called the output.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. What are algorithms ?
Step by step method for problem solving
A process or set of rules to be followed in calculations
or other problem-solving operations, especially by a
computer.
4. Evolution of Algorithm
Origin of algorithm is Persian
attributed to Persian astronomer and
mathematician, Abu Abdullah Muhammad ibn Musa
Al-Khwarizmi
21st century English philosopher used term
“Algorismus”
5. Design of Algorithm
Written as pseudo code or flowchart
What are inputs of problem?
What will be the output of problem?
In what order do instructions need to be carried out
?
What decisions need to be made in problem?
Are any areas of the problem repeated?
6. Need of correctness of algorithm
Algorithm should be correct with respect to a
specification.
Algorithm should yield a required result for every
legitimate input
Should run for finite amount of time
Functional correctness refers to the input-output
behavior of the algorithm
7. Confirming correctness of algorithm
An algorithm Is called totally correct for the given
speciation if and only if for any correct input data it:
1. stops and
2. returns correct output
correct input data is the data which satisfies the initial
condition of the speciation
correct output data is the data which satisfies the final
condition of the speciation
8. Iterative algorithm design issues
Use of loops
1. To establish initial condition
set loop variables to value which are appropriate for
solving smallest instance of problem
2. To find iterative condition
loop variables are changed in every iteration
3. Loop termination
The termination condition occurs when it is known in
prior the number of times is to be iterated
9. Iterative algorithm design issues
Efficiency of algorithm
1. Removing redundant computations outside loop
- When it is embedded in loop
- executed many times unnecessarily
2. Referencing of array element
- Arrays are processed by iterative constructs
3. Inefficiency due to late termination
- When more tests are carried out than required
4. Early detection of designed output conditions
- establishes the desired output condition before general
condition for termination
10. Iterative algorithm design issues
Estimating and specifying Execution time
1. Performance is measured by computational model
2. Reflects the specified input conditions
3. independent of specific programming languages
4. Performance can be measured in terms of size of problem
