String Matching Algorithms String Matching Algorithms are computational methods used to locate specific patterns within text or strings of characters. These patterns could be simple sequences of characters, substrings, regular expressions, or more complex structures. The primary goal of string matching algorithms is to efficiently identify occurrences of a given pattern within a larger text […]

Algorithm Design Techniques Algorithm design techniques are systematic approaches used to create algorithms that efficiently solve specific computational problems. These techniques provide a structured framework for algorithm development, guiding programmers in devising solutions that are not only correct but also optimized for performance, scalability, and resource utilization. or, Algorithm design techniques refer to the methods

Introduction to Sorting Networks A Sorting Network is a parallel sorting algorithm that operates on a fixed number of inputs, arranging them in either ascending or descending order. Unlike traditional comparison-based sorting algorithms such as Quicksort or Merge Sort, which rely on pairwise comparisons to sort elements, sorting networks utilize a series of predetermined comparisons

Introduction to Flow Networks A Flow Networks is a directed graph that represents the flow of some quantity through a network of interconnected nodes and edges. Each edge has a capacity that specifies the maximum amount of flow that can traverse it, and each node acts as a source, sink, or intermediate point through which

Floyd Warshall Algorithm The Floyd Warshall Algorithm is a dynamic programming technique used to solve the all pairs shortest path problem in a weighted graph. Unlike other algorithms like Dijkstra’s or Bellman-Ford, which focus on finding the shortest path from one source node to all other nodes, Floyd-Warshall computes the shortest paths between all pairs

Bellman Ford Algorithm The Bellman Ford Algorithm is a method for finding the shortest path from a single source vertex to all other vertices in a weighted graph. Unlike some other algorithms, such as Dijkstra’s Algorithm, which require non-negative edge weights, Bellman-Ford can handle graphs with negative edge weights, making it a versatile tool in

Dijkstra's Algorithm Dijkstra’s Algorithm is a method used to find the shortest path between nodes in a graph, particularly in weighted graphs where each edge has a numerical weight assigned to it. The algorithm operates by iteratively selecting the vertex with the lowest tentative distance from a source node and updating the distances of its

Minimum Spanning Tree (MST) A Minimum Spanning Tree (MST) is a fundamental concept in graph theory and optimization. It is a subset of the edges of a connected, undirected graph that forms a tree (a connected graph with no cycles) and connects all the vertices together while minimizing the total sum of edge weights. In

Graph Algorithms Graph Algorithms refer to a set of computational techniques and methods designed to analyze, manipulate, and solve problems related to graphs. A graph is a mathematical structure consisting of vertices (nodes) and edges (connections) that link pairs of vertices. Graph algorithms operate on this data structure to uncover patterns, properties, and relationships within

Backtracking Algorithms Backtracking Algorithms are a type of algorithmic technique used to systematically search for solutions to a problem by exploring various potential configurations and backtracking from paths that lead to dead ends. The primary characteristic of backtracking algorithms is their ability to incrementally build a solution candidate, exploring different choices at each step, and
