GRBModel.read()


GRBModel.read()

This method is the general entry point for importing data from a file into a model. It can be used to read basis files for continuous models, start vectors for MIP models, or parameter settings. The type of data read is determined by the file suffix. File formats are described in the File Formats section of the Reference Manual.

Note that this is not the method to use if you want to read a new model from a file. For that, use the GRBModel constructor. One variant of the constructor takes the name of the file that contains the new model as its argument.

void read ( String filename )

    Arguments:

    filename: Name of the file to read. The suffix on the file must be either .bas (for an LP basis), .mst or .sol (for a MIP start), .hnt (for MIP hints), .ord (for a priority order), or .prm (for a parameter file). The suffix may optionally be followed by .zip, .gz, .bz2, or .7z.
