[eclipse-clp-users] Symetric Solution

Hi,

 

I am trying to solve a problem where different items can be packed together
(similar with the bin packing problem). The CLP takes to much time to solve
the problem and I suspect is because of the fact that CLP investigates the
same solution for several times.

 

For example a packing (a, b, c) is equal (a, c, b) but is not equal with (b,
a, c). 

I am wondering how can I formulate this into CLP and / or if there is some
predefined library which can be used?

 

Thanks,

Bogdan.
