Computing Algorithms

A computing algorithm is a set of instructions or a process for solving computational problems. In other words, it contains a set of rules that indicate the step-wise process to solve a problem. The algorithm takes a set of inputs, executes the instructions given to it, and produces the desired output.

Question 2: Three players (A, B and C) play the Card Game. Each player has two cards. The three players have the following card values: Player (A): 5 and 7 Player (B): 4 and 2 Player (C): 8 and 1 Player A starts by putting one card then Player B puts one card then player C puts one card and the game is over. The score of player A (utility value for A) is computed by the following formula: Score(A) = card value(A) - card value(B) - card value(C). The score of player B (utility value for B) is computed by the following formula: Score(B) = card value(B) - card value(A) - card value(C). The score of player C (utility value for C) is computed by the following formula: Score(C) card value(C) - card value(A) - card value(B). a) Construct the corresponding Game Tree. Then find the utility values of all nodes. b) Which player will win the game? c) Show how can the losers make the winner lose the game. What do you note?
