This page contains a list of all file readers which are currently available.
List of readable file formats
The interactive shell and the callable library are capable of reading/parsing several different file formats.
| CIP format | for SCIP's constraint integer programming format |
| CNF format | DIMACS CNF (conjunctive normal form) file format used for example for SAT problems |
| DIFF format | for reading a new objective function for mixed-integer programs |
| FZN format | FlatZinc is a low-level solver input language that is the target language for MiniZinc |
| GMS format | for mixed-integer nonlinear programs (GAMS) [reading requires compilation with GAMS=true and a working GAMS system] |
| LP format | for mixed-integer (quadratically constrained quadratic) programs (CPLEX) |
| MPS format | for mixed-integer (quadratically constrained quadratic) programs |
| OPB format | for pseudo-Boolean optimization instances |
| OSiL format | for mixed-integer nonlinear programs |
| PIP format | for mixed-integer polynomial programming problems |
| SOL format | for solutions; XML-format (read-only) or raw SCIP format |
| WBO format | for weighted pseudo-Boolean optimization instances |
| ZPL format | for ZIMPL models, i.e., mixed-integer linear and nonlinear programming problems [read only] |
