Reasoning as Search

Reasoning as Search. Reasoning. We can describe reasoning as search in a space of possible situations. State Space Search. We need: A set of states A start state A set of operators (a successor function), possibly with costs attached. A set of goal states (or a way to test for goal).

State-Space Search

State-Space Search. Computers should solve problems. A traditional problem domain for AI is the blocks world . Problem description: Given blocks A, B and C, with C on B, arrange the blocks so that A is on B and B is on C. You may only pick up and move one block at a time.
