First, I don't think it would be trivial with whole numbers.

Second, it is relatively easy to solve such a problem for a (very) small number of weights, but it is known to be a very difficult problem when the number of weights grows larger. In fact, most computer scientists believe that there is probably no workable solution for just a few hundred random values (brute force would probably take billions of years to calculate because of an exponential explosion). In other words, the ability to solve such a problem depends very much on your input data, especially on the number of weights that you have (and also on the data shape). Please provide as much detailed information on the input data as you can (especially the maximum number of values).
