Get feasible solution from Couenne after time limit (JuMP)

[odow]

This is probably the same issue as Couenne reports problem as optimal on time-limit · Issue #160 · jump-dev/AmplNLWriter.jl · GitHub. See also

Julia/JuMP - Couenne: How to get intermediate or best feasible solutions when TIME_LIMIT has been reached? - Stack Overflow.

I think this is an upstream problem in Couenne. The bad news is that it’s unlikely to get fixed anytime soon.

I’d suggest you try a different MINLP solver, like GitHub - lanl-ansi/Juniper.jl: A JuMP-based Nonlinear Integer Program Solver.
