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 structure, search is just gue
