Question

Your task is to get all the blue marbles in P1 and red marbles in P2

The actions available are as follows:

ܘܐ ܙP 22

• You can move 2 marbles from P1 to P2 if they are of the same color (either you can move 2 red or you can move 2 blue)
• You can move 2 marbles from P2 to P1 if they are each of different colors (one blue or one red)

Give the PDDL description to represent the above as a Planning Problem. Do not forget to also define and describe the predicates and constants that your are going to use.

Also, give a complete plan (using the actions described) for getting from the start to the goal state

Planning Problem

ܘܐ ܙP 22

This problem will be solves in 6 steps-

1. Initialy- P1-3 Red Balls , P2= 3 Blue balls

here i will Mention Red Balls as R and Blue Balls as B.

2. Move 2 R balls from P1 to P2-

Result- P1=R , P2=BBBRR

3. Move 2 balls B and R from P2 to P1-

Result- P1=RRB , P2=BBR

4. Move 2 balls B and R from P2 to P1-

Result- P1=RRBBR , P2=B

5. Move 2 balls R and R from P1 to P2-

Result- P1=BBR , P2=BRR

6. Move 2 balls B and R from P2 to P1-

Result- P1=BBRRB , P2=R

7. Move 2 balls R and R from P1 to P2-

Result- P1=BBB , P2=RRR

Therefor all the balls have been moves in just 6 simple steps.
