Question 1
STATE SPACE
Recall the rabbits crossing puzzle from the practice assignment. Two groups of rabbits, each group at opposite ends of a path, want to cross the path by making only forward jumps: a rabbit can jump forward to an adjacent empty spot, or jump forward over one rabbit and land in an empty spot.
The start state is (RR-L) , where R is a rabbit that wants to go right, and L is a rabbit that wants to go left, and the dash marks the empty spot.
Construct all the states that are reachable from the start state and build a state space graph out of those states, call it Graph-21.
Based on the above data, answer the given subquestions.
Which of the following states are reachable from the start state in exactly 3 moves?
(RL–R)
(–RLR)
(–RRL)
(–LRR)
(L–RR)
