Hi Igor,

I don't know if you are required to use finite domain to solve this 
problem, but the tutorial chapter for the Column Generation library in 
the ECLiPSe tutorial describes how to model and solve such 1-dimensional 
cutting stock problem using the library. This of course is not a finite 
domain solution to the problem.

Cheers,

Kish
