Hi Kish, do I understand you correctly, you want to first minimize one cost variable, and then (independently) minimize another? I.e., when the first one is minimized, there's potentially still variables left that are not assigned, and then you branch over them, minimizing the other? Or

Hi, I am now trying to add support for the minimising search engines (BAB, Restart) to the ECLiPSe-Gecode interface I am developing. I think I can see how to implement the cost function, which is only given at run-time (with the limitation that the cost is a finite domain variable, which has m
