http://ycpcs.github.io/cs360-spring2015/lectures/lecture14.html WebGreedy approach is used to find the solution to maximize the count of activities that are to be execute. Using this approach, activity is choose with an earliest finish time at each step in way to get an optimal solution. Below is the example of Activity Selection Problem with input- output constraint and the solution for the example.
WebTheorem 17.1: Algorithm Greedy-Activity-Selector produces solutions of maximal size for the activities-selection problem. Proof: Let S = { 1, 2, ... n }, are sorted 1 has the earliest finishing time. We wish to show there is an optimal solution that begins with activity 1. Suppose A S is an optimal solution and the first activity is k 1. WebActivity selection problem is a problem in which a person has a list of works to do. Each of the activities has a starting time and ending time. We need to schedule the activities in such a way the person can complete a …
