Webknapsack contains items 1 and 3 (total: $46). As we shall see in Chapter 8, neither version of this problem is likely to have a polynomial-time algorithm. However, using dynamic programming they can both be solved in O(nW) time, which is reasonable when W is small, but is not polynomial since the input size is proportional to logWrather than W. only prettier by miranda lambertWebdef unbounded_knapsack_dp_memoization(weights, profits, capacity): memory = [ [None] * (capacity + 1) for i in range(len(weights))] item_index = 0 return unbounded_knapsack_dp_memoization_util(weights, profits, capacity, item_index, memory) def unbounded_knapsack_dp_memoization_util(weights, profits, capacity, item_index, … only pretty what a pity
