ex) car navigation figuring out the pathways

State Bases:

This can be now presented with nodes:

How can we determine if the AI had achieve its goal state? It can be test with goal test.

ex) If the destination matches with the user’s typed keywords, then it had reached the goal state.

Path cost: numerical cost associated with a give path, it’s telling AI to find one path that can be less expensive and efficient

Solution would be a sequence of actions that leads from the initial state to a goal state
