**subset_sum_swap_test**,
a Fortran90 code which
calls subset_sum_swap(), 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.
