WebAs what we said earlier, the greedy best-first search algorithm tries to explore the node that is closest to the goal. This algorithm evaluates nodes by using the heuristic function h(n), that is, the evaluation function is equal to the heuristic function, f(n) = h(n). This equivalency is what makes the search algorithm ‘greedy.’ WebFeb 23, 2024 · The above pseudo code shows the basic structure of a greedy algorithm. The first step is to set the current state to the initial state of the problem. Next, we keep looping until the current state is equal to the goal state. Inside the loop, we choose the next state that we want to move to. This is done by using a function called chooseNextState().
