Problem solving agent

•Goal formulation:

   Based on current situation and the agent’s performance measure-first step in problem solving.

•Problem formulation:

   Deciding what actions and state to consider, given a goal.

•An agent with several immediate options of unknown value can decide what to do by first examining different possible sequences of actions that lead to state of known value and then choosing the best sequence.-Search.

•Search algorithm-problem as input and returns the solution in the form of sequence.

•Solution found, action carried out-execution phase.
