> because we are considering adding this package as a dependency I don't think @martinbiel is planning on putting a lot of effort into StochasticPrograms in the long-term, so I'd...

SCIP should set `z[j]` to binary when adding an indicator constraint, and then potentially error on `optimize!` if the user has not explicitly set `z` to be binary.

I think it's something to do with how we were setting options. If you use the defaults, everything passes: https://github.com/jump-dev/HiGHS.jl/blob/de218441bc179f1489f470d3c3b4aa943974cc34/test/MOI_wrapper.jl#L27-L45 If you force the algorithm, there were failures: https://github.com/jump-dev/HiGHS.jl/blob/de218441bc179f1489f470d3c3b4aa943974cc34/test/MOI_wrapper.jl#L47-L82 But...

See https://github.com/ERGO-Code/HiGHS/pull/970. These failures are expected.

Instead of deleting the nonlinear constraints, we can just keep track of how many constraints have been added: ```Julia + offset = get(m.ext, :MCP_EXPRESSIONS_ADDED, 0) + for i in (offset+1):n...

This is still a problem in SHOT 1.1. ```Julia julia> model = Model() do AmplNLWriter.Optimizer(SHOT_jll.amplexe) end A JuMP Model Feasibility problem with: Variables: 0 Model mode: AUTOMATIC CachingOptimizer state: EMPTY_OPTIMIZER...

Julia now has a binary build system called Yggdrasil (https://github.com/JuliaPackaging/Yggdrasil), which cross compiles open-source binaries for a wide variety of platforms. I've been attacking MINLP solvers recently, so now you...

> DIPOPT_INC_DIR:PATH=/path/to/ipopt/include -DIPOPT_LIB_DIR:PATH=/path/to/ipopt/lib, -DASL_INC_DIR:PATH, -DASL_LIB_DIR:PATH Perfect! This will do nicely. So what is the minimal set of dependencies that we would need? Just ASL, Cbc, Ipopt? > Building on windows...

Awesome! I'll take a look. How stable is minotaur with Cbc/Ipopt compared to the other solvers? Is it possible to link CPLEX at runtime? Or does it have to be...

Thanks for this info! I'll try an open-source version for now and leave CPLEX out of it.
