Constrain solutions to integers? #20

Open IanButterworth opened 3 years ago

IanButterworth commented 3 years ago

Is there an existing way to constrain the sampling to integer positions? I have a domain that can't be sampled finer than integers.

I didn't see a convenient way to do so. I did wonder about scaling the domain down to eps steps, setting minwidth to eps, then scaling it back up but haven't got that working yet

Sorry for the delay. There isn't, currently. Do you have a lot of integers you need to try? If not, then just computing the objective for all seems sensible.

I have all these backburner projects to make this package a lot better, but they've never advanced beyond back-burner and are still a long ways from primetime. My JuliaCon poster was one small piece of that effort.
