It is a well established fact that merge sort runs faster than insertion sort. Using asymptotic analysis we can prove that merge sort runs in O(nlogn) time and
What is a Randomized Algorithm? An algorithm that uses random numbers to decide what to do next anywhere in its logic is called Randomized Algorithm.. For examp
Why performance analysis? There are many important things that should be taken care of, like user friendliness, modularity, security, maintainability, etc. Why
In the previous post, we discussed how Asymptotic analysis overcomes the problems of naive way of analyzing algorithms. In this post, we will take an example of
We have discussed Asymptotic Analysis, and Worst, Average and Best Cases of Algorithms. The main idea of asymptotic analysis is to have a measure of efficiency
The main idea of asymptotic analysis is to have a measure of efficiency of algorithms that doesn’t depend on machine specific constants, mainly because this a
We have discussed Asymptotic Analysis, Worst, Average and Best Cases and Asymptotic Notations in previous posts. In this post, analysis of iterative program
In the previous post, we discussed analysis of loops. Many algorithms are recursive in nature. When we analyze them, we get a recurrence relation for time comp
Amortized Analysis is used for algorithms where an occasional operation is very slow, but most of the other operations are faster. In Amortized Analysis, we ana

We have introduced and discussed below Karger’s algorithm in set 1. 1) Initialize contracted graph CG as copy of original graph 2) While there are more than 2
When an input string (source code or a program in some language) is given to a compiler, the compiler processes it in several phases, starting from lexical anal
FIRST(X) for a grammar symbol X is the set of terminals that begin the strings derivable from X. Rules to compute FIRST set: If x is a terminal, then FIRST(x) =
Lexical Analysis is the first phase of compiler also known as scanner. It converts the High level input program into a sequence of Tokens. Lexical Analysis can

It is the analysis of flow of data in control flow graph, i.e., the analysis that determines the information regarding the definition and use of data in program
This article demonstrates an illustration of K-means clustering on a sample random data using open-cv library. Pre-requisites: Numpy, OpenCV, matplot-lib Let’
1. Univariate data – This type of data consists of only one variable. The analysis of univariate data is thus the simplest form of analysis since the informat
Amortized analysis refers to determining the time-averaged running time for a sequence (not an individual) operation. It is different from average case analysis
Background A Database Management System (DBMS) stores data in the form of tables, uses ER model and the goal is ACID properties. For example a DBMS of college h
