Shortest Path Problem
The Shortest Path Problem is a fundamental algorithmic problem in graph theory and computer science that involves finding the shortest path between two nodes (vertices) in a graph, where the path's length is typically defined as the sum of the weights of its edges. It has applications in various fields such as network routing, transportation, and robotics. Common algorithms to solve it include Dijkstra's algorithm, Bellman-Ford algorithm, and A* search, each with different assumptions about edge weights and graph properties.
Developers should learn this concept when working on applications that require optimization of routes or distances, such as GPS navigation systems, logistics planning, or network analysis. It is essential for solving real-world problems like finding the quickest travel route, minimizing costs in supply chains, or designing efficient communication networks, making it a core skill in algorithm design and data structures.
