docplex.mp.model_stats module¶

class docplex.mp.model_stats.ModelStatistics[source]¶

Bases: object

This class gathers statistics from the model.

Instances of this class are returned by the method docplex.mp.model.Model.get_statistics().

The class contains counters on the various types of variables and constraints in the model.

property number_of_binary_variables¶: This property returns the number of binary decision variables in the model.

property number_of_continuous_variables¶: This property returns the number of continuous decision variables in the model.

property number_of_eq_constraints¶: This property returns the number of == constraints

property number_of_equivalence_constraints¶: This property returns the number of equivalence constraints.

docplex.mp.constr.EquivalenceConstraint

property number_of_ge_constraints¶: This property returns the number of >= constraints

property number_of_indicator_constraints¶: This property returns the number of indicator constraints.

docplex.mp.constr.IndicatorConstraint

property number_of_integer_variables¶: This property returns the number of integer decision variables in the model.

property number_of_le_constraints¶: This property returns the number of <= constraints

property number_of_linear_constraints¶

This property returns the total number of linear constraints in the model.

This number comprises all relational constraints: <=, ==, and >= and also range constraints.

property number_of_quadratic_constraints¶: This property returns the number of quadratic constraints.

docplex.mp.constr.QuadraticConstraint

property number_of_range_constraints¶

This property returns the number of range constraints.

Range constraints are of the form L <= expression <= U.
