[eclipse-clp-users] code problem

Hi,

I am trying to solve a problem and the code is quite ugly.

I am expecting the code to run forever and after a while I receive the
following error:
 type error in max([], _3320)

I believe (from printed messages) the error is related to chooseMaxGroup
but I am not able to fix it. 

Any suggestion is more than welcomed.

Best regards,
Bogdan.
