Knapsack Problem: 0-1 and Fractional Using Dynamic Programming

WebAnother simple case to consider would be if i = 0 or c = 0. If i = 0, there are no items to consider so V(0, c) = 0.If c = 0, the knapsack can not hold anything else, so V(i,0) = 0.. Next consider how to define V(i, c) in terms of small parameter values when i > 1.A good way to break this down is as follows: If WT(i) > c then V(i, c) must be the same as V(i-1, c) since … WebWrite, Run & Share C Language code online using OneCompiler's C online compiler for free.
