I am trying to use user-defined functions with the MathOptNLSModel for solving nonlinear least squares problems. I use: using JuMP using NLPModelsJuMP using JSOSolvers model = Model() g(x...) = 10*length(x) + sum(x[i].^2 .- 10*cos.(2π*x[i]) for i in 1:length(…

Thanks @blob .
I posted the issue on their GitHub https://github.com/JuliaSmoothOptimizers/NLPModelsJuMP.jl/issues/94 and the problem is now fixed.
