Hi Amine,

The time-out for bb_min applies to the bb_min it is in. Your program 
calls bb_min many times, and each bb_min seem to fail very quickly (much 
less than the 10 second time-out), that is why you don't time-out.

You are calling bb_min many times because you have created many 
choice-points when you posted your constraints before bb_min (as you 
create alternative constraints to post with ;). Normally, this style of 
programming (having many choice-points when you post your constraints) 
is not a recommended style for constraint programming.

Cheers,

Kish
