Knapsack Problem (Actually, this is a subset of real knapsack problem.... - there's nothing to optimize!) The knapsack problem is: Given positive integers , and an integer S, find non-negative integers satisfies ... or in (my bad) English... Suppose you have many stuffs which weights , find configurations of those stuffs which weights S. Problem Find all configurations of stuffs, which information is given by input. Input You can make your own format, but you should enable users to input...
Answer:
Python, 185 chars S,C,N=input() R=range(len(C)) F=lambda i,w:sum([[x+[j]for x in F(j,w-C[j])]for j in...

Currently there exists a way to print out one possible solution. However I want print out all solutions in O(nC) time, where n is the number of items and C is the total capacity of the knapsack. If there is, can you also describe the algorithm in pseudocode...
Answer:
Slightly off topic - as everyone had mentioned, there is no way to enumerate all the solutions in O...

Actually I got confused because, in one website I saw people dividing the items in to fraction and in one site, I saw that problem is solved keeping in mind that objects can't be divided! What is the actual knapsack problem rule? Update: thank you to...
Answer:
Yes you can divide the items and that is the category of Fractional Knapsack problem. And another category...

I am trying to understand if the *exact 0-1 knapsack problem* is also pseudo-polynomial time. Some clarifications: We are given n stones of varying and known weights, and some number W. We need to find any subset of the stones (if it exists) that sum...
Answer:
This is just the subset sum problem, and there is an obvious O(N*W) algorithm. Let the weights of stones...

More formally, say, we have 2 sacks with capacities c1 and c2. There are N items with profits pi and weights wi. As in 0-1 Knapsack problem, we need to fill in c1 and c2 with these items in such a way the overall profit is maximized. Assume pi and wi...
Answer:
In the usual knapsack problem, we would define a variable best[i][j] as the maximum profit we could...
