Shell Sort Algorithm

Shell Sort Algorithm sorts elements in array at a specific interval. At first, it sorts the elements that are away from each other and successively reduces the interval between them. Shell Sort is named after Donald Lewis Shell who initially wrote it in a research paper called A High-Speed Sorting Procedure.

C Algorithms Library

This article is about a collection of common Computer Science algorithms which may be used in C projects. The C Programming Language has a much smaller Standard Library as compared to other more modern programming languages such as Java or Python. The library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O.

Find the middle element of linked list in C

In order to find middle element of linked list in one pass, you need to maintain two pointers, one increment at each node while other increments after two nodes at a time. By having this arrangement, when first pointer reaches end, second pointer will point to middle element of linked list.

Free Programming Abstractions Course – SEE

Stanford Engineering Everywhere (SEE) offers few computer science courses to students online and at no charge. Programming Abstractions course covers advanced programming topics such as recursion, algorithmic analysis, and data abstraction using the C++ programming language, which is similar to both C and Java.

Kruskal’s Algorithm Implementation in C

This is the implementation of Kruskal’s Algorithm in C Programming Language. This algorithm is directly based on the generic MST (Minimum Spanning Tree) algorithm. Kruskal’s algorithm is a greedy algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. It finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized.

Porter’s Algorithm in C

Originally written in 1979 at Computer Laboratory, Cambridge (England), it was reprinted in 1997 in the book “Readings in Information Retrieval”. Initially it was written in BCPL language. Here is the list of implementations in other programming languages including C, Java and Pearl implementations done by author himself.

Algorithms in C

These algorithms are represented in terms of compact implementations in C so that readers can both understand their fundamental properties and implement them in real applications. The method of the analysis of algorithms is quite carefully designed. When appropriate, analytic results are described to explain why certain algorithms are preferred. In some cases, the practical algorithms’ relationship being discussed to purely theoretical results is also described.
