Implementation-wise, a 2D DP is relatively easy. With some math, the problem itself can be converted to a subset sum problem (LC416). Thank you very much! It took a whole hour to understand the first example) I had to write an example in python to get intermediate results and understan...

This project has been developed for academic purpose. Basically, it consists in a Python algorithm able to solve a multidimensional Knapsack problem using only Gomory cuts. Every new cut shows its utility in terms of how much it reduces the gap between t
This is an implementation of the 0-1 knapsack problem in C using a recursive approach. The problem consists of a set of items, each with a weight and a value, and a knapsack with a maximum weight capacity. The goal is to determine the subset of items that maximizes the total value of...
