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.
