Hi,

I am trying to solve a loading/unloading problem which looks like 2D rectangular packing with additional constraints, e.g. of scheduling type. Moreover, the packed objects have variable size in one dimension (which is time).

What software is recommended, ILOG CP 1.6 or CP Optimizer? I started looking at ILOG CP. It has classes named as Ilo... and Ilc... and I see no documentation about their difference and what is the concept to use them. Just isolated examples in the manuals. I can only understand that Ilc... allow some managing...

What would be a sensible way to model non-overlapping constraints for rectangles (whose size in the 1st dimension is variable)? I mean how to do it efficiently, e.g., is there any version of diff2 available?

Would be great to have help,

Gleb
