Hello :smiley: I am using JuMP to solve a chance-constrained optimization, the original package is very old and I met issues of reproducing it. Following is one package I am trying to solve but stuck for more than a week: jacobians.jl These few lines use MathProgBase, which is no longer used now…

Hi @SSGD , welcome to the forum. See Computing Hessians · JuMP . You need to adapt it slightly to make: julia> using JuMP, Ipopt, SparseArrays julia> function build_nlp_evaluator(model) rows = Any[] nlp = MOI.Nonlinear.Model() for (F, S) in list_of_constraint_types(…

Struggle at using JuMP/MathOptInterface for calculating number of constraints

The @NL macros are part of the legacy interface. You should change them to use @constraint instead.

For information on the new nonlinear interface, see:

JuMP 1.15.0 is released | JuMP
ANN: JuMP v1.15 is released
