WebIpopt (Interior Point Optimizer, pronounced ‘’Eye-Pea-Opt’’) is an open source software package for large-scale nonlinear optimization. It is designed to find (local) solutions of mathematical optimization problems of the form. min x ∈ R n f ( x) subject to. g L ≤ g ( x) ≤ g U x L ≤ x ≤ x U. Where x are the optimization ... WebTo install ipopt on an anaconda environment, you just need to open an anaconda terminal, activate the environment you wish to install ipopt on, then type: "conda install -c conda-forge ipopt", then proceed normally as you would in installing other packages.
