[Ipopt] How to make Ipopt faster when all variables have 1e-4 precision?

try setting the option "tol" to a larger value

I'm not sure if multiplying by 1e4 has any effect, perhaps someone can
comment on if ipopt is using scaled primal/dual tolerances or unscaled

What do you mean "say that they are integers"? I'm not aware of this
