Question 1 : ( 5 0 pts ) Consider the Differentiated Set Coverage Problem: Input: n items, U = ( 1 , 2 . .
Question : pts Consider the Differentiated Set Coverage Problem: Input: n items, U n coverage requirements of the items f S m sets, S Sz Sm price of the sets p PP Pm Let x Im be the selection decisions of the sets, Output: A minimum price selection x of the sets Si Sa Sm that can cover the items in U at least f times. Ex: Let n and U having coverage requirements f Let m and S S S Ss Ss with prices p For instance, item ; U should be covered by at least different sets S We note that item can be covered by S with price pi by S with price p and by S with priceps pts Determine a greedy selection rule for the sets. Design a greedy algorithm for the Differentiated Set Coverage Problem and report the pseudocode. pts Discuss the time complexity of your greedy algorithm. Is it efficient? Can your algorithm find the optimum solution?
