Optgra
This repository provides pyoptgra, a python package wrapping (and including) OPTGRA. OPTGRA is an optimization algorithm developed and implemented by Johannes Schoenmaekers, it is specifically designed for near-linear constrained problems, which commonly occur in trajectory optimization.
The full documentation can be found here or on the ESA-internal page.
Installation
With Pip
Pyoptgra is available on PyPi and can be installed with pip:
pip install pyoptgra
Compile from Source
First install a C++ compiler, a fortran compiler, cmake, python and python build, then clone the repository and build with python -m build
Usage
Pyoptgra is designed as a pygmo user-defined algorithm: First create an instance of the optgra class with all relevant parameters, then pass a pygmo.population containing your problem to the instance’s evolve method:
>>> import pygmo >>> import pyoptgra >>> prob = pygmo.problem(pygmo.schwefel(30)) # using the schwefel test problem from pygmo, with 30 dimensions >>> pop = pygmo.population(prob, 1) >>> algo = pygmo.algorithm(pyoptgra.optgra()) >>> pop = algo.evolve(pop) # the actual call to OPTGRA
