[Coin-announce] A new library for algebraic modeling in C++ : Rehearse

[Onur Çelebi]

I am happy to announce the release of Rehearse, an algebraic modeling
library in C++,
that has been added to the COIN-OR repository  :
https://projects.coin-or.org/Rehearse

It works in a very similar way to the equivalent proprietary ILOG Concert ©
library.

In particular :

 * It helps you to build your model using native C++ expressions, for
example :

        CelNumVar x1;
        CelNumVar x2;

        model.setObjective (       7 * x1 + 9 * x2 );

        model.addConstraint(       1 * x1 +     x2 == 18  );
        model.addConstraint(                    x2 <= 14  );
        model.addConstraint(       2 * x1 + 3 * x2 <= 50  );

 * It supports multi dimensional variable arrays, for example : x[i][j][k]
<= 3
 * Expressions are interpreted dynamically so you can build them in C++

CelExpression expr;

  for (int j=0; j<L; j++){
  expr += x[i][j];
  }

  model.addConstraint( expr <= 1 );

 * It is released under MIT license.


The source code and some examples are available on COIN-OR's github page :
https://github.com/coin-or/Rehearse

If you want to try it, download_dependencies.sh will download other COIN-OR
projects
dependencies via svn, then you can use the classical ./configure, make,
make test, make install.
