Ford-Fulkerson Algorithm . In computer science, mutual exclusion is a property of concurrency control, which is instituted for the purpose of preventing race conditions.It is the requirement that one thread of execution never enters a critical section while a concurrent thread of execution is already accessing said critical section, which refers to an interval of time during which a thread of execution accesses a In computer science, a search algorithm is an algorithm (if more than one, algorithms) designed to solve a search problem.Search algorithms work to retrieve information stored within particular data structure, or calculated in the search space of a problem domain, with either discrete or continuous values..

In numerical analysis, Newton's method, also known as the NewtonRaphson method, named after Isaac Newton and Joseph Raphson, is a root-finding algorithm which produces successively better approximations to the roots (or zeroes) of a real-valued function.The most basic version starts with a single-variable function f defined for a real variable x, the function's derivative f , Dijkstra shortest path algorithm using Prims Algorithm in O(V 2):. John Hopcroft brought everyone at the The following is simple idea of Ford-Fulkerson algorithm: Start with initial flow as 0. Note: A vertex in an undirected connected graph is an articulation point (or cut vertex) if removing it (and edges through it) disconnects the graph.Articulation points represent vulnerabilities in a connected network single points whose failure would split the network into 2 or more components. In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A.
