The ZIB Optimization Suite is a tool for generating
and solving mixed integer programs. It consists of the following parts
| ZIMPL |
a mixed integer programming modeling language |
| SoPlex |
a linear programming solver |
| SCIP |
a mixed integer programming solver and constraint programming framework. |
The user can easily generate linear programs and mixed
integer programs with the modeling language
ZIMPL. The resulting model can directly be loaded
into SCIP and solved. In the solution process SCIP
may use SoPlex as underlying LP solver.
Since all three tools are available in source code
and free for academic use, they are an ideal tool for academic research purposes and
for teaching integer programming.
See ZIB licences for more information.
