subset_sum_swap, an Octave code which uses swapping to try to improve an initial estimated solution of the subset sum problem, which seeks a subset of a set of integers which has a given sum. Even when an exact solution exists, this approach often only finds an approximate solution.
In the test code, we will be 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, or comes very close to it.
