Stuart Russell & Peter Norvig
A kind of Goal-based agent.
Decide what to do by searching sequence of actions that lead to desirable states.
Problem Definition :-
Initial state : starting point
Operator : description of an action
State space : all states reachable from the initial state by any sequence action
Path : Sequence of actions leading from one state to another
Goal test : Which the agent can apply to a single state description to determine if it is a goal state
Path cost function : Assign a coast to a path which the sum of the costs of the individual actions along the path.
