optymus is a Python library designed to address optimization problems in science and engineering. Built on JAX, allowing automatic differentiation for efficient computation of gradients and Hessians. The library emphasizes ease of use and flexibility, enabling users to solve optimization problems with minimal setup. optymus also provides robust capabilities for visualization and benchmarking, allowing users to gain insights into method behavior and compare performance effectively.

Getting Started

To begin using optymus, follow these steps:

1. Install optymus:

   pip install optymus --upgrade # update version
   pip install optymus[all] # all dependencies
   pip install optymus[methods] # without plot dependencies

2. Get Started:

   from optymus import Optimizer
   from optymus.benchmark import MccormickFunction
   
   import jax.numpy as jnp
   
   f = MccormickFunction()
   initial_point = jnp.array([2, 2])
   
   opt = Optimizer(f_obj=f,
                   x0=initial_point,
                   method='bfgs')
   
   opt.report()

3. Explore the Documentation: Visit the official documentation to understand the available optimization methods and how to use them effectively.

Refer to the documentation for detailed information on each method and its application.
