Working with multiple models
The Gurobi shell allows you to work with multiple models simultaneously. For example...
gurobi> a = read('/opt/gurobi912/linux64/examples/data/p0033')
Read MPS format model from file /opt/gurobi912/linux64/examples/data/p0033.mps
Reading time = 0.00 seconds
P0033: 16 Rows, 33 Columns, 98 NonZeros.
gurobi> b = read('/opt/gurobi912/linux64/examples/data/stein9')
Read MPS format model from file /opt/gurobi912/linux64/examples/data/stein9.mps
Reading time = 0.00 seconds
STEIN9: 13 Rows, 9 Columns, 45 NonZeros.
The models() command gives a list of all active models.
gurobi> models() Currently loaded models: a : <gurobi.Model MIP instance P0033: 16 constrs, 33 vars, Parameter changes: LogFile=gurobi.log> b : <gurobi.Model MIP instance STEIN9: 13 constrs, 9 vars, Parameter changes: LogFile=gurobi.log>
Note that parameters can be set for a
particular model with the Model.setParam() method or the
Model.Params
class, or they can be changed for all models in the
Gurobi shell by using the global setParam() method.
