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 … Webthe same running time, is greedy, and is also therefore another optimal solution. 16.1-3 Not just any greedy approach to the activity-selection problem produces a maximum-size set of mutually compatible activities. Give an example to …

WebSelect all the answers below which are TRUE The running time of the GREEDY-ACTIVITY-SELECTOR (s,f) algorithm is O (n) if the input activities are not sorted. A greedy algorithm is a top-down approach. Let Z be an LCS of two sequences X and Y. Then the length of Z is at most min (length X, length Y) All greedy choices lead to optimal solutions.
