GRBModel()
Constructor for GRBModel
. The simplest version creates an
empty model. You can then call
addVar and
addConstr to populate
the model with variables and constraints. The more complex
constructors can read a model from a file, or make a copy of an
existing model.
GRBModel | GRBModel ( | const GRBEnv& | env ) |
Model constructor.
Arguments:
env: Environment for new model.
Return value:
New model object. Model initially contains no variables or constraints.
GRBModel | GRBModel ( | const GRBEnv& | env, |
const string& | filename ) |
Read a model from a file. Note that the type of the file is encoded
in the file name suffix. Valid suffixes are .mps
,
.rew
, .lp
, .rlp
, .dua
, .dlp
,
.ilp
, or .opb
. The files can be compressed, so
additional suffixes of .zip
, .gz
, .bz2
, or
.7z
are accepted.
Arguments:
env: Environment for new model.
modelname: Name of the file containing the model.
Return value:
New model object.
GRBModel | GRBModel ( | const GRBModel& | model ) |
Create a copy of an existing model. Note that due to the lazy update approach in Gurobi, you have to call update before copying it.
Arguments:
model: Model to copy.
Return value:
New model object. Model is a clone of the input model.
