How Graph Structure Makes AI Search Possible

AI search does not start with an algorithm. It starts with structure. Before BFS, DFS, A*, or heuristics can work, the problem must first become something searchable. That is where graphs come in. Core Idea Many AI problems can be represented as graphs. A graph gives the problem a structure: states become nodes relationships become edges possible moves become paths goals become target nodes Once the problem has this form, search algorithms can operate on it. Without structur...
