@ronaldvdv-gurobi, thank you for looking into this! While your approach is indeed a far simpler implementation, mainly for performance reasons, this ultimately needs to be designed as a writer that...

@ronaldvdv-gurobi, the reason to do a new one is that the current `gurobi_direct_v2` only supports linear problems and can handle *very* large linear problems since it is aware of templatized...

@ronaldvdv-gurobi, if you have a few minutes, could I have your help? I merged in your tests (on [this branch](https://github.com/emma58/pyomo/tree/gurobi-minlp)), and 4 of them are failing with my current implementation:...

This is a good thing to do! Regarding your questions: - The default `Var` domain is `Reals`, with lb and ub both `None`. - The default `Param` domain is currently...

@whart222, if you're ready for me to start looking at this would you run `black`? Then the rest of the tests will run. Thank you!

@jlgearh, @whart222, I just opened #3342 to track planned changes not addressed in this PR. Please make sure I didn't miss anything when you get a chance.

@ZedongPeng could you please run `black` on this so we can see if other tests are passing?

Hi @ZedongPeng, it also looks like the Jenkins failures are real. Here's the stack trace: ``` self = @unittest.skipUnless( SolverFactory('gams').available() and SolverFactory('gams').license_is_valid(), "gams solver not available", ) def test_solve_four_stage_dynamic_model(self): model...

@jsiirola this is probably my fault, but I can't figure out how at the moment. :P

@blnicho, probably, yes. I mostly just wanted to document it since we're thinking about solver things and I don't know how standard these rules are. I do think the error...
