$A^*$ algorithm uses $f’=g+h’$ to estimate the cost of getting from the initial state to the goal state, where $g$ is a measure of cost getting from initial state to the current node and the function $h’$ is an estimate of the cost of getting from the current node to the goal state. To find a path involving the fewest number of steps, we should test, $g=1$ $g=0$ $h’=0$ $h’=1$
