# The devel/ruby-subset_sum,ruby24 port

## ruby24-subset_sum-1.0.2p0 – simple subset sum problem solver for ruby

## Description

    This module provides both a C and pure ruby simple subset sum problem
    solver. The subset sum problem is, given a set of numbers, can the sum
    of any subset of those numbers equal a given number. This problem is
    NP-complete.

    Both the C and pure ruby versions implement a fairly simple
    meet-in-the-middle algorithm. The C version uses an AVL tree to store
    the data, while the pure ruby version uses a ruby hash. For the C
    version to be used, the sum of the positive numbers and the sum of the
    negative numbers in the set, as well as the wanted number, must all be
    Fixnums. Additionally, max_seconds should be nil or a Fixnum.
