WebIn computer science, a problem is said to have optimal substructure if an optimal solution can be constructed efficiently from optimal solutions to its subproblems. [1] This property … Web2.0.1 Optimal substructure To solve a optimization problem using dynamic programming, we must rst characterize the structure of an optimal solution. Speci cally, we must prove …
WebNov 21, 2024 · If the optimal solution to a problem can be obtained using the optimal solution to its subproblems, then the problem is said to have optimal substructure property. As an example, let’s consider the problem of finding the shortest path between ‘Start’ and ‘Goal’ nodes in the graph below. 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 …
