2. Specifying the environment (ODESA D)

1- Observability ( Fully Observable vs. Partial Observable)

Fully Observable

2- Deterministic vs. stochastic.

Deterministic

3- Episodic vs. Sequential.

Sequential.

4- Static vs. dynamic.

Static

5- Agents (Single agent vs. multi-agent)

Single agent

3- The formulation:

§ States:

Aget can be in two location left or right

Aget can take only one of wolf,sheep or cabbage to cross one of them river

§ Initial state:

Wolf ,sheep and cabbage at the right cross of the river

And the man is behind them

§ Successor function:

Takes one of wolf ,sheep and cabbage  to cross river

§ Goal test:

Wolf ,sheep and cabbage cross the river

§ Path cost:

 number of steps in the path (each step costs 1)
