Evomatic

Evomatic is an genetic algorithm tool for the development of new alloys.

Installation

The evomatic package can be installed from pypi using pip:

pip install evomatic

Evomatic makes heavy use of the metallurgy package to manipulate and approximate properties of alloys. The cerebral package can be used by evomatic to obtain predictions of alloy properties on-the-fly during evolution.

Usage

Basic usage of evomatic involves setting some targets and running an evolution, the following example shows evolution of a small population towards alloys with high mass:

>>> import evomatic as evo

>>> evolver = evo.Evolver(targets={"maximise": ["mass"]}, population_size=50)

>>> history = evolver.evolve()

>>> history["alloys"]

In this simple example, there is no better material for the objective of maximum mass than pure Oganesson.
