alg quiz Consider the following generalization of the Activity Selection Problem: You are given a set of n activities each with a start time si, a finish time fi, and a weight wi. Design a dynamic programming algorithm to find the weight of a set of non-conflicting activities with maximum weight. - ANSWER-Formula: (Sort by finish time) A[i] = max (from activity 1 to i) { A[i - 1] max{A[x]} + wi } (x being activity whose finish time <= activity i's start time) A contiguous subseque...
