Optimal substructure property is utilized by
WebOptimal substructure is a core property not just of dynamic programming problems but also of recursion in general. If a problem can be solved recursively, chances are it has an optimal substructure. Optimal substructure simply means that you can find the optimal solution to a problem by considering the optimal solution to its subproblems. 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.
