Greedy activity selector
WebActivity Selection: A Greedy Algorithm • The algorithm using the best greedy choice is simple: – Sort the activities by finish time – Schedule the first activity – Then schedule the next activity in sorted list which starts after previous activity finishes – Repeat until no more activities • Or in simpler terms: – Always pick the compatible activity that finishes … WebCSE5311 Greedy_DP 3 Activity Selection Problem • Scheduling a resource among several competing activities. • S = {1,2, 3, …, n} is the set of n proposed activities • The activities share a resource, which can be used by only one activity at a time -a Tennis Court, a Lecture Hall etc., • Each activity i has a start time, si and a ...

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 can be solved by Greedy-Iterative-Activity-Selector Algorithm. The basic idea is to always pick the next activity whose finish time is least among the remaining activities and the start time is more than or equal to the finish time of previously selected activity. We can sort the activities according to their ...
