MathOptInterface.BarrierIterations

[nsajko]

The README suggests setting the iteration limit like so:

MOI.set(moi_model, MOI.RawOptimizerAttribute("IPM_IterationsLimit"), 200)

I think, however, that perhaps this is supposed to have the same effect:

MOI.set(moi_model, MOI.BarrierIterations(), 200)

The latter call fails like so:

julia> using Tulip, MathOptInterface

julia> const MOI = MathOptInterface
MathOptInterface

julia> lp = Tulip.Optimizer{BigFloat}()
Tulip.Optimizer{BigFloat}

julia> MOI.set(lp, MOI.BarrierIterations(), 100)
ERROR: MathOptInterface.SetAttributeNotAllowed{MathOptInterface.BarrierIterations}: Setting attribute MathOptInterface.BarrierIterations() cannot be performed. You may want to use a `CachingOptimizer` in `AUTOMATIC` mode or you may need to call `reset_optimizer` before doing this operation if the `CachingOptimizer` is in `MANUAL` mode.
