Yes, changes to recomputation can change the variable ordering but that's the best we can do.I think quite some variable selection strategies will also work differently on different hardware/software platforms due to different rounding...
To me, changing the amount of recomputation is somewhat different from running on different hardware/software platforms. Am I correct that besides activity, changing the amount of recomputation will only affect memory/execution performance?
Is it not possible to turn off the gathering of activity information during recomputation? I assume that (like in our interface code), you know when you are performing recomputation, and if so, can the gathering of activity information be turned off for the duration?
How about one can give an initialization function for Activity such that the activity value will be initialized for each variable. That should be easy.
This sound like a good idea! Cheers, Kish _______________________________________________ Gecode users mailing list users@gecode.org https://www.gecode.org/mailman/listinfo/gecode-users
