Import optimization data from a file. This routine is the general entry point for importing data from a file into a model. It can be used to read start vectors for MIP models, basis files for LP models, or parameter settings. The type of data read is determined by the file suffix. File formats are described in the File Format section.
Return value:
A non-zero return value indicates that a problem occurred while reading the file. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
Arguments:
model: The model that will receive the start vector.
filename: The path to the file to be read. The suffix on the file must be either .mst or .sol for a MIP start file, .hnt for a MIP hint file, .ord for a priority order file, .bas for a basis file, or .prm for a parameter file, The suffix may optionally be followed by .zip, .gz, .bz2, or .7z.
Example usage:
error = GRBread(model, "/tmp/model.mst.bz2");
