This document provides an introduction to the Master Theorem, which can be used to determine the asymptotic runtime of recursive algorithms. It presents the three main conditions of the Master Theorem and examples of applying it to solve recurrence relations. It also notes some pitfalls in using the Master Theorem and briefly introduces a fourth condition for cases where the non-recursive term is polylogarithmic rather than polynomial.
Divide and Conquer Algorithms - D&C forms a distinct algorithm design technique in computer science, wherein a problem is solved by repeatedly invoking the algorithm on smaller occurrences of the same problem. Binary search, merge sort, Euclid's algorithm can all be formulated as examples of divide and conquer algorithms. Strassen's algorithm and Nearest Neighbor algorithm are two other examples.

A grammar is said to be regular, if the production is in the form -
A → αB,
A -> a,
A → ε,
for A, B ∈ N, a ∈ Σ, and ε the empty string
A regular grammar is a 4 tuple -
G = (V, Σ, P, S)
V - It is non-empty, finite set of non-terminal symbols,
Σ - finite set of terminal symbols, (Σ ∈ V),
P - a finite set of productions or rules,
S - start symbol, S ∈ (V - Σ)

In computer science, divide and conquer (D&C) is an algorithm design paradigm based on multi-branched recursion. A divide and conquer algorithm works by recursively breaking down a problem into two or more sub-problems of the same (or related) type, until these become simple enough to be solved directly. The solutions to the sub-problems are then combined to give a solution to the original problem.
In computer science, merge sort (also commonly spelled mergesort) is an O(n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output. Mergesort is a divide and conquer algorithm that was invented by John von Neumann in 1945. A detailed description and analysis of bottom-up mergesort appeared in a report by Goldstine and Neumann as early as 1948.
Business value of business models
Requirements for software development
Requirements provide a description of what a proposed software application should do. Without detailed requirements, application development projects fail. Business models capture this detail in a way that is understandable to both the business users and the software developers. Business users do not need to understand how the system will be created; they need to understand how it will support their need. Business models are a better form of requirements for end users.

What is a business model?
A business model is a simple representation of the complex reality of a particular organization.
Business models are useful for understanding how a business is organized, who interacts with whom, what goals and strategies are being pursued, what work the business performs, and how it performs that work.

Master Theorem I
When analyzing algorithms, recall that we only care about the
asymptotic behavior.
Recursive algorithms are no different. Rather than solve exactly
the recurrence relation associated with the cost of an
algorithm, it is enough to give an asymptotic characterization.
The main tool for doing this is the master theorem.

Theorem (Master Theorem)
Let T(n) be a monotonically increasing function that satisfies
T(n) = aT(n
b ) + f(n)
T(1) = c
where a ≥ 1, b ≥ 2, c > 0. If f(n) ∈ Θ(nd) where d ≥ 0, then
T(n) =
Θ(nd) if a < bd
Θ(nd log n) if a = bd
Θ(nlogb a) if a > bd

Pitfalls
You cannot use the Master Theorem if
T(n) is not monotone, ex: T(n) = sin n
f(n) is not a polynomial, ex: T(n) = 2T(n
2 ) + 2n
b cannot be expressed as a constant, ex: T(n) = T(
√
n)
Note here, that the Master Theorem does not solve a
recurrence relation.
Does the base case remain a concern?

4th Condition
“Fourth” Condition
Recall that we cannot use the Master Theorem if f(n) (the
non-recursive cost) is not polynomial.
There is a limited 4-th condition of the Master Theorem that
allows us to consider polylogarithmic functions.
Corollary
If f(n) ∈ Θ(nlogb a logk
n) for some k ≥ 0 then
T(n) ∈ Θ(nlogb a
logk+1
n)
This final condition is fairly limited and we present it merely for
completeness.
