Thanks @fredrikekre

I'm away this weekend, but will test next week. Failures on Julia 1.6 and 1.7 are expected, but 1.8 is more stable. On Sat, 20 Aug 2022, 10:28 am Carleton...

`Highs_resetGlobalScheduler` is now in the C API as part of HiGHS v1.3.0.

This works: ```Julia julia> using HiGHS julia> Highs_resetGlobalScheduler(1) julia> model = HiGHS.Optimizer() A HiGHS model with 0 columns and 0 rows. julia> x = MOI.add_variable(model) Running HiGHS 1.3.0 [date: 1970-01-01,...

In fact, we don't support start values at all (the first start value is silently ignored by HiGHS). I've updated the title to reflect that.

I talked to @blegat, and we should also look into why MOI threw an error here, instead of ignoring it.

This requires `setHotStart` to be exposed upstream: https://github.com/ERGO-Code/HiGHS/blob/437c98b08710433d8a2052d341f6250b17a016c5/src/Highs.h#L933-L937 Requires `setSolution`, which was added https://github.com/ERGO-Code/HiGHS/commit/ecf9b931f8e8604cbe561ac750afeb53e7ad8f7c but isn't in a released version yet.
