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. Give a search formulation to the problem of looking for both gold and diamond in a Knowing that you have M squares in the maze that do not have an What is the maximum size of the state space. What is the maximum branching For each of the following heuristics, indicate (yes/no) whether or not it is h1: The number of dots (representing food) remaining.

To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:
1-Let’s say you have a variable with a static graph associated with it in the backend that will be executed every time you call .compute on that variable. Is there any way to avoid re-computation of the graph every time you call the .compute method? Consider that you have a significant amount of storage available in this case.
ADT Graph Iterator: Create either a DFS graph iterator or a BFS graph iterator by implementing java.util.lterator interface. An ADT graph iterator should have a reference to an ADT graph. It should also have a DFS search method or a BFS search method.
