◆ ExportModelAsLpFormat()

absl::StatusOr<std::string> operations_research::ExportModelAsLpFormat ( const MPModelProto &  model,
const MPModelExportOptions &  options = MPModelExportOptions() 
)

Outputs the current model (variables, constraints, objective) as a string encoded in the so-called "CPLEX LP file format" as generated by SCIP.

The LP file format is easily readable by a human.

Returns false if some error has occurred during execution. The validity of names is automatically checked. If a variable name or a constraint name is invalid or non-existent, a new valid name is automatically generated.

If 'obfuscated' is true, the variable and constraint names of proto_ are not used. Variable and constraint names of the form "V12345" and "C12345" are used instead.

For more information about the different LP file formats: http://lpsolve.sourceforge.net/5.5/lp-format.htm The following give a reasonable idea of the CPLEX LP file format: http://lpsolve.sourceforge.net/5.5/CPLEX-format.htm http://tinyurl.com/cplex-lp-format http://www.gurobi.com/documentation/5.1/reference-manual/node871

◆ ExportModelAsMpsFormat()

absl::StatusOr<std::string> operations_research::ExportModelAsMpsFormat ( const MPModelProto &  model,
const MPModelExportOptions &  options = MPModelExportOptions() 
)

Outputs the current model (variables, constraints, objective) as a string encoded in MPS file format, using the "free" MPS format.

Returns false if some error has occurred during execution. Models with maximization objectives trigger an error, because MPS can encode only minimization problems.

The validity of names is automatically checked. If a variable name or a constraint name is invalid or non-existent, a new valid name is automatically generated.

Name validity and obfuscation works exactly as in ExportModelAsLpFormat().

◆ ExtractValidMPModelInPlaceOrPopulateResponseStatus()

bool operations_research::ExtractValidMPModelInPlaceOrPopulateResponseStatus ( MPModelRequest *  request,
MPSolutionResponse *  response 
)

Like ExtractValidMPModelOrPopulateResponseStatus(), but works in-place: if the MPModel needed extraction, it will be populated in the request, and it returns the success boolean.

◆ ExtractValidMPModelOrPopulateResponseStatus()

absl::optional<LazyMutableCopy<MPModelProto> > operations_research::ExtractValidMPModelOrPopulateResponseStatus ( const MPModelRequest &  request,
MPSolutionResponse *  response 
)

If the model is valid and non-empty, returns it (possibly after extracting the model_delta).

If invalid or empty, updates response and returns null.

◆ FindErrorInMPModelDeltaProto()

std::string operations_research::FindErrorInMPModelDeltaProto ( const MPModelDeltaProto &  delta,
const MPModelProto &  model 
)

Like FindErrorInMPModelProto, but for a MPModelDeltaProto applied to a given baseline model (assumed valid, eg.

FindErrorInMPModelProto(model)=""). Works in O(|model_delta|) + O(num_vars in model), but the latter term has a very small constant factor.

◆ FindErrorInMPModelProto()

std::string operations_research::FindErrorInMPModelProto ( const MPModelProto &  model,
double  abs_value_threshold = 0.0 
)

Returns an empty string iff the model is valid and not trivially infeasible.

Otherwise, returns a description of the first error or trivial infeasibility encountered.

abs_value_threshold is the (exclusive) limit for the abs value of constraint coefficients, objective coefficients, etc. If unspecified, or 0, it defaults to FLAGS_model_validator_infinity.

NOTE(user): the code of this method (and the client code too!) is considerably simplified by this string-based, simple API. If clients require it, we could add a formal error status enum.

◆ FindFeasibilityErrorInSolutionHint()

std::string operations_research::FindFeasibilityErrorInSolutionHint ( const MPModelProto &  model,
double  tolerance 
)

Returns an empty string if the solution hint given in the model is a feasible solution.

Otherwise, returns a description of the first reason for infeasibility.

This function can be useful for debugging/checking that the given solution hint is feasible when it is expected to be the case. The feasibility is checked up to the given tolerance using the ::operations_research::IsLowerWithinTolerance() function.
