WebGreedy Choice Greedy Choice Property 1.Let S k be a nonempty subproblem containing the set of activities that nish after activity a k. 2.Let a m be an activity in S k with the earliest nish time. 3.Then a m is included in some maximum-size subset of mutually compat- ible activities of S k. Proof Let A kbe a maximum-size subset of mutually compatible activities … WebFor example, Huffman encoding scheme is a greedy approach, but it does not exhibit matroid structure. To prove a greedy algorithm, in general, you need to show that your solution exhibits -1) optimal substructure property as in DP and 2) The choice made by a greedy approach is not sub-optimal (basically show that it is optimal or one of the ...
