Hi,

I hope you're all well, and thoroughly enjoying your IJCAI reviewing!

I'm working on Savile Row's Gecode (flatzinc) output -- I have a type in SR for negative table constraints (i.e. the tuple set represents the disallowed tuples). I don't see anything that looks relevant in registry.cpp. Obviously turning it into a positive table constraint is an exponential explosion.

I could decompose into one constraint per tuple -- but of course this is horrible for propagation.

Can you suggest anything better?

Thanks,
Peter
