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. In computer science, a problem is said to have optimal substructure if an optimal solution can be constructed from optimal solutions of its subproblems. This property is used to determine the usefulness of greedy algorithms for a problem. Typically, a greedy algorithm is used to solve a problem with optimal … See more Consider finding a shortest path for traveling between two cities by car, as illustrated in Figure 1. Such an example is likely to exhibit optimal substructure. That is, if the shortest route from Seattle to Los Angeles passes … See more A slightly more formal definition of optimal substructure can be given. Let a "problem" be a collection of "alternatives", and let each alternative have an associated cost, c(a). The task is to … See more • Longest path problem • Addition-chain exponentiation • Least-cost airline fare.
