- agents: An agent is trying to eat all the food in a maze that contains obstacles, but he now has the help of his friends! An agent cannot occupy a square that has an obstacle. There are initially k pieces of food (represented by dots), at positions (f1,...,fk). There are also n agents at positions (p1,...,pn). Initially, all agents start at random locations in the maze. Consider a search problem in which all agents move simultaneously ;that is, in each step each agent moves into some adjacent position (N, S, E, or W, or STOP). Note that any number of agents may occupy the same position. Figure 1: A maze with 3 agents For each of the following heuristics, indicate (yes/no) whether or not it is h1: The number of dots (representing food) remaining. [ True, False ]. h2(s)=0, where s is a state node. [ True, False ]. h3(s)=1, where s is a state node.

- CS Fundamentals of AI Use the alpha-beta pruning for 13 marbles for the "1-2 steal marbles ". Please give me the decision tree and the pseudocode about 13 marbles. PS: "1-2 steal marbles " Initially, there are 6 marbles on the board. One of the players can choose to remove 1 or 2 marbles leaving 5 or 4, after that the other player can do the same, choosing to take again one or two marbles from the board. The process continue until there is only one marble in the board. The player who wins is the one the leaves the last marble on the board. (For example: If there are 3 marbles and it's my turn , then I will choose to remove 2 to leave one in the board to win)arrow_forwardThe Jaccard coefficient between two sets {a, b, c, d} and {a, b, c, e} is 0.75.
