How Search Algorithms Work — From DFS and BFS to A*

Search algorithms look simple until the state space gets huge. Then the real question becomes: Do you explore everything, or do you choose smarter paths first? That is the core idea behind search in AI. Core Idea Search is about moving from a start state to a goal state. You have: a current state possible actions next states a goal condition The algorithm decides which state to explore next. That one decision changes everything. The Basic Structure Most search al...
