Activity Selection problem and Greedy Algorithm - Coding Ninjas
WebJun 14, 2024 · The following is my understanding of why greedy solution always words: Assertion: If A is the greedy choice (starting with 1st activity in the sorted array), then it gives the optimal solution. Proof: Let there be another choice B starting with some activity k (k != 1 or finishTime (k)>= finishTime (1)) which alone gives the optimal solution.So ... WebAlgorithm 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 1. We want to ... signify littlestown pa

WebActivity Selection (1) I Consider the problem of scheduling classes in a classroom I Many courses are candidates to be scheduled in that room, ... greedy choice 10/24 Greedy-Activity-Selector(s,f,n) 1 A={a1} 2 k =1 3 for m=2to n do 4 if s[m]f[k]then 5 A= [{am} 6 k =m 7 8 end 9 returnA What is the time complexity? 11/24 Example WebIn order to determine which activity should use which lecture hall, the algorithm uses the GREEDY-ACTIVITY-SELECTOR to calculate the activities in the first lecture hall. If there are some activities yet to be scheduled, a new lecture hall is selected and GREEDY-ACTIVITY-SELECTOR is called again. This continues until all activities have been ... 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 ... the purpose of discrimination legislation
