Working with multiple models
The Gurobi shell allows you to work with multiple models simultaneously. For example...
gurobi> a = read('c:/gurobi560/win64/examples/data/p0033') Read MPS format model from file c:/gurobi560/win64/examples/data/p0033.mps Reading time = 0.00 seconds P0033: 16 Rows, 33 Columns, 98 NonZeros. gurobi> b = read('c:/gurobi560/win64/examples/data/stein9') Read MPS format model from file c:/gurobi560/win64/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> b : <gurobi.Model MIP instance STEIN9: 13 constrs, 9 vars>
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.
