Designan evaluation function for Chess (or Go, Othello, checkers) that depends on at least four factors. i.e. f(State) = w1 * f1 + w2 * f2 + w3 * f3 + w4 * f4 + ellipsis. Describe each factor in details with examples. Implement your function in a program that reads a state from a file and loads it in a suitable state representation. The program computes the function. The program should read whether the evaluation will be in favor of the White or Black side. Bonus: Implement also the move generator. Construct a general alpha-beta game-playing agent that uses your implementation. Compare the effect of increasing search depth, improving move ordering, and improving the evaluation function. How close does your effective branching factor come to the ideal case of perfect move ordering
