File Readers

Detailed Description

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]
