Update coefficients in an exsiting model easily

[Zhanwei-Liu]

Hi,

Does PyOptInterface have a function akin to pyomo's Param (mutable=Ture) that allows for easy updating of model coefficients? Alternatively, does anyone have suggestions on how to update the coefficients in a model using PyOptInterface?

Best Regards,

No, full support for parameter is a complex issue. Even JuMP.jl does not have a complete solution for this problem.

However, for linear constraints, we provide methods to modify its coefficients and right-hand side directly as documented in https://metab0t.github.io/PyOptInterface/constraint.html#modify-constraint
