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. WebThe knapsack problem exhibitsthe optimal substructure property: Let i k be the highest-numberd item in an optimal solution S= fi 1;:::;i k 1;i kg, Then 1. S0= Sf i kgis an optimal solution for weight W w i k and items fi 1;:::;i k 1g 2. the value of the solution Sis v i k +the value of the subproblem solution S0 4/10
