Your Answer
*** FAIL: ./test_cases/q1/graph_backtrack.test *** graph: *** B *** ^ *** | *** *A --> C --> G *** | *** V *** D *** *** A is the start state, G is the goal. Arrows mark *** possible state transitions. This tests whether *** you extract the sequence of actions correctly even *** if your search backtracks. If you fail this, your *** nodes are not correctly tracking the sequences of *** actions required to reach them. *** student solution: ['1:A->C', '0:C->G'] *** student expanded_states: ['A', 'D', 'C', 'G'] *** *** correct solution: ['1:A->C', '0:C->G'] *** correct expanded_states: ['A', 'D', 'C'] *** correct rev_solution: ['1:A->C', '0:C->G'] *** correct rev_expanded_states: ['A', 'B', 'C']
