Feature - consider already existing parts stock #4

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
I studied a little bit the litterature about cutting stock problem and I'm
wondering if could be too difficult to add existing stock (parts already
cutted) to the main problem.

If object(s), bar(s), or roll(s) are already cut into parts of specified 
widths, then
count of those widths can be reduced from demand count for those widths. 
Remaining
demand figures could be used and fed to cspsol.

If cspsol return you a optimal solution with number of patterns = N. Then final
solutions consists of these N patterns + M (say) patterns that were already cut.

So this request need not be cspsol's feature.
