Investigate Switching TestOptimizer to use Cascades (and whether or not we want to) #152

Closed jurplel closed 7 months ago

jurplel commented 7 months ago

Currently it uses the heuristic optimizer. It seems that to use the cascades optimizer, we might need to introduce a more advanced dummy cost model. It might also be the case that we want to just keep testing on the heuristic optimizer.

See #140 for context.

I think we can use two phase now, no need for using heuristic rules to test cascades. Some rules are not well designed for cascades and jignesh agrees on that too.

Ok, I'll just close this issue for now then. Thanks for your feedback!
