WebbThe state space forms a graph in which nodes are states and the ares between nodes art actions. A path in the state space is a sequence of states connected by a sequence of actions. 3] The goal test, which determines whether a given state is a goal state. 4] A path cost function that assigns a numeric cost to each path.
