Subject Artificial intelligence
Which of the following are true and which are false? Explain your answers. 1. Depth-first search always expands at least as many nodes as A search with an admissible heuristic. 2. h(n)=0h(n)=0 is an admissible heuristic for the 8-puzzle. 3. A is of no use in robotics because percepts, states, and actions are continuous. 4. Breadth-first search is complete even if zero step costs are allowed. 5. Assume that a rook can move on a chessboard any number of squares in a straight line, vertically or horizontally, but cannot jump over other pieces. Manhattan distance is an admissible heuristic for the problem of moving the rook from square A to square B in the smallest number of moves.
