%global _empty_manifest_terminate_build 0 Name: python-ecos Version: 2.0.12 Release: 1 Summary: This is the Python package for ECOS: Embedded Cone Solver. See Github page for more information. License: GPLv3 URL: http://github.com/embotech/ecos Source0: https://mirrors.nju.edu.cn/pypi/web/packages/04/da/aefd27c06a9179a7e5614d0d97c0384072d2d22800790690c661eb6f2f4a/ecos-2.0.12.tar.gz Requires: python3-numpy Requires: python3-scipy %description # Python Wrapper for Embedded Conic Solver (ECOS) [![Build Status](http://github.com/embotech/ecos-python/workflows/build/badge.svg?event=push)](https://github.com/embotech/ecos-python/actions/workflows/build.yml) **Visit www.embotech.com/ECOS for detailed information on ECOS.** ECOS is a numerical software for solving convex second-order cone programs (SOCPs) of type ``` min c'*x s.t. A*x = b G*x <=_K h ``` where the last inequality is generalized, i.e. `h - G*x` belongs to the cone `K`. ECOS supports the positive orthant `R_+` and second-order cones `Q_n` defined as ``` Q_n = { (t,x) | t >= || x ||_2 } ``` In the definition above, t is a scalar and `x` is in `R_{n-1}`. The cone `K` is therefore a direct product of the positive orthant and second-order cones: ``` K = R_+ x Q_n1 x ... x Q_nN ``` ## Installation The latest version of ECOS is available via `pip`: pip install ecos This will download the relevant wheel for your machine. ### Building from source If you are attempting to build the Python extension from source, then use make install This will use the latest tag on git to version your local installation of ECOS. You will need [Numpy](http://www.numpy.org/) and [Scipy](http://www.scipy.org/). For installation instructions, see their respective pages. You may need `sudo` privileges for a global installation. ### Windows users Windows users may experience some extreme pain when installing ECOS from source for Python 2.7. We suggest switching to Linux or Mac OSX. If you must use (or insist on using) Windows, we suggest using the [Miniconda](http://repo.continuum.io/miniconda/) distribution to minimize this pain. If during the installation process, you see the error message `Unable to find vcvarsall.bat`, you will need to install [Microsoft Visual Studio Express 2008](go.microsoft.com/?linkid=7729279), since *Python 2.7* is built against the 2008 compiler. If using a newer version of Python, you can use a newer version of Visual Studio. For instance, Python 3.3 is built against [Visual Studio 2010](http://go.microsoft.com/?linkid=9709949). ## Calling ECOS from Python After installing the ECOS interface, you must import the module with ``` import ecos ``` This module provides a single function `ecos` with one of the following calling sequences: ``` solution = ecos.solve(c,G,h,dims) solution = ecos.solve(c,G,h,dims,A,b,**kwargs) ``` The arguments `c`, `h`, and `b` are Numpy arrays (i.e., matrices with a single column). The arguments `G` and `A` are Scipy *sparse* matrices in CSR format; if they are not of the proper format, ECOS will attempt to convert them. The argument `dims` is a dictionary with two fields, `dims['l']` and `dims['q']`. These are the same fields as in the Matlab case. If the fields are omitted or empty, they default to 0. The argument `kwargs` can include the keywords + `feastol`, `abstol`, `reltol`, `feastol_inacc`, `abstol_innac`, and `reltol_inacc` for tolerance values, + `max_iters` for the maximum number of iterations, + the Booleans `verbose` and `mi_verbose`, + `bool_vars_idx`, a list of `int`s which index the boolean variables, + `int_vars_idx`, a list of `int`s which index the integer variables, + `mi_max_iters` for maximum number of branch and bound iterations (mixed integer problems only), + `mi_abs_eps` for the absolute tolerance between upper and lower bounds (mixed integer problems only), and + `mi_rel_eps` for the relative tolerance, (U-L)/L, between upper and lower bounds (mixed integer problems only). The arguments `A`, `b`, and `kwargs` are optional. The returned object is a dictionary containing the fields `solution['x']`, `solution['y']`, `solution['s']`, `solution['z']`, and `solution['info']`. The first four are Numpy arrays containing the relevant solution. The last field contains a dictionary with the same fields as the `info` struct in the MATLAB interface. ## Using ECOS with CVXPY [CVXPY](http://cvxpy.org) is a powerful Python modeling framework for convex optimization, similar to the MATLAB counterpart CVX. ECOS is one of the default solvers in CVXPY, so there is nothing special you have to do in order to use ECOS with CVXPY, besides specifying it as a solver. Here is a small [example](http://www.cvxpy.org/en/latest/tutorial/advanced/index.html#solve-method-options) from the CVXPY tutorial: ```py import cvxpy as cp # Solving a problem with different solvers. x = cp.Variable(2) obj = cp.Minimize(cp.norm(x, 2) + cp.norm(x, 1)) constraints = [x >= 2] prob = cp.Problem(obj, constraints) # Solve with ECOS. prob.solve(solver=cp.ECOS) print("optimal value with ECOS:", prob.value) ``` ## ECOS Versioning The Python module contains two version numbers: 1. `ecos.__version__`: This is the version of the Python wrapper for ECOS 2. `ecos.__solver_version__`: This is the version of the underlying ECOS solver These two version numbers should typically agree, but they might not when a bug in the Python module has been fixed and nothing in the underlying C solver has changed. The major version numbers should agree, however. ### What happened to 2.0.7? Because version-syncing ECOS and ECOS-Python can be tricky, the 2.0.7 version did not incorporate some minor changes to ECOS. In an ill-advised move, the release was deleted in hopes it could be re-uploaded, despite plenty warnings stating otherwise. Instead, a post release has been made that contains identical content to the 2.0.7 release. Generally, `pip` should pick up the post release for 2.0.7 and any dependencies such as `pip install "ecos>=2.0.5"` should still work as expected. ## Deployment When creating new versions of the Python wrapper, please use `bumpversion` to bump the version number and also remember to tag the commit so that CI is able to properly pick it up. See [Release](RELEASE.md) for more information. ## Python2 Support Starting with version 2.0.8, ecos-python will no longer support Python2.7. You may be able to download an [older version](https://github.com/embotech/ecos-python/releases/tag/2.0.7.post1) but moving forward we will no longer publish Python2 wheels for use. ## License ECOS is distributed under the [GNU General Public License v3.0](http://www.gnu.org/copyleft/gpl.html). Other licenses may be available upon request from [embotech](http://www.embotech.com). ## Credits The solver is essentially based on Lieven Vandenberghe's [CVXOPT](http://cvxopt.org) [ConeLP](http://www.ee.ucla.edu/~vandenbe/publications/coneprog.pdf) solver, although it differs in the particular way the linear systems are treated. The following people have been, and are, involved in the development and maintenance of ECOS: + Alexander Domahidi (principal developer) + Eric Chu (Python interface, unit tests) + Stephen Boyd (methods and maths) + Michael Grant (CVX interface) + Johan Löfberg (YALMIP interface) + João Felipe Santos, Iain Dunning (Julia interface) + Han Wang (ECOS branch and bound) The main technical idea behind ECOS is described in a short [paper](http://www.stanford.edu/~boyd/papers/ecos.html). More details are given in Alexander Domahidi's [PhD Thesis](http://e-collection.library.ethz.ch/view/eth:7611?q=domahidi) in Chapter 9.
