WebQuestion: 4. In Chapter 15 Section 4, the CLRS texbook discusses a dynamic programming solution to the Longest Common Subsequence (LCS) problem. In your own words, explain the optimal substructure property: Theorem 15.1 (Optimal substructure of an LCS) Let X (*1, X2, ..., Xm) and Y (y1, y2, ..., Yn) be sequences, and let Z = (Z1, Z2, ..., Zk) be any LCS of X … WebBoth exhibit the optimal substructure property, but only the second also exhibits the greedy-choice property. Thus the second one can be solved to optimality with a greedy algorithm (or a dynamic programming algorithm, although greedy would be faster), but the first one requires dynamic programming or some other non-greedy approach.
WebSorted by: 11 There is no (one) formal definition of "optimal substructure" (or the Bellman optimality criterion) so you can not possibly hope to (formally) prove you have it. You … 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 …
