subset_sum_brute


subset_sum_brute, a MATLAB code which illustrates how a subset sum problem can be solved by exhaustive search.

We are given a collection of (21) weights and a target value (24639098). We seek a combination of the weights which adds up to the target value.

The function subset_sum_brute.m simply considers every possible subset of the weights, determines its sum, and compares that to the target value. The first case in which the target value is matched is returned as the solution.

This program, which solves the problem serially, is primarily intended to be a starting point for a parallel programming approach.
