Accesing Lagrange multipliers while using Ipopt from Nonconvex.jl

Specific Domains Optimization (Mathematical)
1

I was trying Nonconvex.jl using Ipopt. Is there a way in which I can access Lagrange multipliers?

The Lagrangian multipliers can be accessed using:

result.problem.mult_g
result.problem.mult_x_L
result.problem.mult_x_U

The first is all the multipliers associated with the inequality constraints followed by the equality constraints in the order in which they were added. The second is the multipliers associated with the variables’ lower bounds. The third is the multipliers associated with the variables’ upper bounds.
