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, .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.
