Many references are made to sims.
I take this to mean that a computer program exists that can compile statistical information based on input "constraints" as applied to bridge.
Presumably, data related to distribution, hcp, is fed in and out pops the results.

I would appreciate more info on this topic. Ease of use?, cost?, how might the results be applied? etc.

I have DealmasterPro. Got it for sixty-something bucks and I have really enjoyed it. One of my best buys ever. I know some people cook their own programs. But if you're asking about ease of use I bet you're better with DM.

You can create hands for tournaments, you can create hands using constraints, you can input a hand or two and ask the program to deal several hands with some constraints but that fixed hand or hands. This is what a simulation would consist of.

I use tommy andrew's program. Free, but you have to program stuff yourself. A bit geeky, but it works.
