I copied the code you published into VICE and was disappointed to get nothing 
but an OUT OF DATA ERROR IN 6050.
Trying to figure out what's missing, I realized that the site you linked to 
merely gives a tiny example that's already solved in place.
So I guess they give the additional problem data only to those who register 
(which I won't).
Does the challenge consist in writing a fully general solution to the 
mathematical problem? Or are they content if your program can solve the given 
major problem?
Would it be a lot of work to devise a problem instance that is too hard to 
solve by hand but still can be solved by a standard Commodore 128 within a few 
minutes?
