    1 = Welcome to the COIN-OR/GAMS links homepage =
    2 
    3 == Introduction ==
    4 
    5 This project is dedicated to the development of links between [http://www.gams.com GAMS] ('''G'''eneral '''A'''lgebraic '''M'''odeling '''S'''ystem) and open source solvers.
    6 The links are written in C++ and are released as open source code under the Eclipse Public Licence (EPL) 1.0.
    7 The COIN-OR project leader for GAMSlinks is [http://www.gams.com/~stefan Stefan Vigerske] (GAMS Software GmbH).
    8 
    9 Currently the following links are available:
    10 
    11   * [https://projects.coin-or.org/Bonmin Bonmin]: Basic Open-source Nonlinear Mixed-Integer Programming
    12   * [https://projects.coin-or.org/Couenne Couenne] Convex Over and Under Envelopes for Nonlinear Estimation
    13   * [https://projects.coin-or.org/Cbc Cbc]: Coin Branch and Cut code
    14   * [https://projects.coin-or.org/Ipopt Ipopt]: Interior Point Optimizer
    15   * [https://projects.coin-or.org/Osi Osi]: Interface to LP and MIP solvers with an Open Solver Interface, currently CPLEX, Gurobi, Mosek, and Xpress
    16   * [https://projects.coin-or.org/OS OS]: Optimization Services
    17   * [http://soplex.zib.de SoPlex]: Sequential object-oriented simPlex
    18   * [http://scip.zib.de SCIP]: Solving Constraint Integer Programs
    19 
    20 Note, that these solver links are also distributed with any regular GAMS distribution.
    21 
    22 Note, that one still requires a **licensed GAMS base system** to use the solvers via GAMS.
    23 
    24 == Download / Installation ==
    25 
    26 The links should work under Linux and Mac OS X (both 64 bit), and maybe Windows.
    27 
    28 The latest version is available in trunk. The stable branches do not receive much updates.
    29 You can obtain GAMSlinks/trunk via subversion by typing
    30 {{{
    31 svn checkout https://projects.coin-or.org/svn/GAMSlinks/trunk GAMSlinks
    32 }}}
    33 See also the [https://projects.coin-or.org/BuildTools/wiki/user-download COIN-OR documentation for the download of source code] and [https://projects.coin-or.org/BuildTools/wiki/current-issues current issues] for building COIN-OR code. Especially the build under Windows 32 bit is difficult and not suggested.
    34 
    35 Please '''read the detailed installation instructions''' in the '''INSTALL file'''.
    36 
    37 == Usage / Documentation ==
    38 
    39 After installing the COIN-OR solvers in your GAMS system (see INSTALL file), you can use the COIN-OR solvers as every other GAMS solver.
    40 For example, to use Ipopt as an NLP solver, you can use the following statement (before the solve statement) inside your GAMS program to specify using Ipopt:
    41 {{{
    42   Option NLP = MyIpopt;
    43 }}}
    44 Another way is to give the argument {{{NLP=MyIpopt}}} to your gams call.[[BR]]
    45 For more information we refer to the [http://www.gams.com/latest/docs GAMS documentation].
    46 
    47 For a '''documentation''' of the GAMS/COIN-OR links and their '''parameters''' please see the [http://www.gams.com/latest/docs/S_MAIN.html GAMS solver manuals].
