Welcome to NoLOAD_Jax’s documentation!

Introduction to NoLOAD_Jax

NoLOAD_Jax stands for Non-Linear Optimization using Automatic Differentiation with Jax package. It aims to be a light non-linear optimization tool for energy components and systems. It is an Open Source project located on GitLab at NoLOAD Gitlab, with available open benchmark examples at NoLOAD benchmark Gitlab
