SDPA for Python

Interior-point SDP solver for Python

SDPA for Python is a Python 3 wrapper for SDPA (SemiDefinite Programming Algorithm). SDPA is a software package for solving general SDPs based on primal-dual interior-point methods with the HRVW/KSH/M search direction [1].

This package is a fork of SDPAP, the Python interface for SDPA provided at the official SDPA website. This repository aims to provide Python 3 support for both SDPA and SDPA Multiprecision (fork of SDPA-GMP [4]).

Getting Started

Installation

Two variants of this package are available on the Python Package Index (PyPI). The package using the SDPA (OpenBLAS) backend can be installed by

pip install sdpa-python

The package using the SDPA Multiprecision (GMP) backend can be installed by

pip install sdpa-multiprecision

For supported platforms, please see the Installation section.

Usage

To get started, see the Usage section.

History

SDPA was officially developed between 1995 and 2012 by Makoto Yamashita, Katsuki Fujisawa, Masakazu Kojima, Mituhiro Fukuda, Kazuhiro Kobayashi, Kazuhide Nakata, Maho Nakata and Kazushige Goto [1] [2] [3]. The official SDPA website contains an unmaintained version of SDPA.

SDPAP was written by Kenta Kato as a Python 2 interface for SDPA. The official SDPA website also contains an unmaintained version of SDPAP.

This package is a Python 3 port of SDPAP. Besides Python 3 support, it also adds support for the multiprecision backend.
