A Python Library for Classical and Dynamical Low-Rank CMA-ES

---

General :earth_americas:

seamaze is a Python library for classical and Dynamical Low-Rank (DLR) CMA-ES variants. It is designed to navigate complex, high-dimensional fitness landscapes by iteratively adapting a multivariate Gaussian search space to the objective's local topography. By leveraging DLR approximations, seamaze remains computationally efficient even on ill-conditioned or rugged black-box problems. This implementation further extends to the integration of first-order information, constraints, and robust restart mechanisms.

Usage

seamaze has two main classes which provide a classical and a dynamical low-rank CMA-ES variant:

Classical CMA-ES

from seamaze.cmaes import CMAES

Dynamical low-rank CMA-ES

from seamaze.dlrcmaes import DLRCMAES
