Algorithm for fractional knapsack1. W and item have value Vi and weight Wi. 2. Rank item by value/weight ratio: Vi/Wi. 3. Thus : Vi/Wi= Vj/Wj for all i<=Wj. 4. Consider items in order of descending ratio. 5. Take as much of each item is possible. 6. Assume value and ...

As a diversion we return in this chapter to another (once) promising public-key encryption scheme using a trap-door function: Knapsack encryption. It, too, is based on residue arithmetic, but uses multiplication rather than exponentiation, making it easi
We can express this fact in the following formula: define c[i, w] to be the solution for items 1,2, , i and the maximum weight w.The algorithm takes the following inputsThe maximum weight W The number of items n The two sequences v = <v1, v2, , vn> and w = <w1, w2, ,...
Very good problem to learn knapsack (complete knapsack in this case). My brutal-force solution in Python got AC too, which surprised me a bit. Here is the ideal DP solution. Just check comments: T =int(input())for_inrange(0, T): ...
