docplex.mp.vartype module

class docplex.mp.vartype.BinaryVarType

Bases: docplex.mp.vartype.VarType

This class models the binary variable type and is not meant to be instantiated. Each model contains one instance of this type.

is_discrete()

Checks if this is a discrete type.

Returns:True as this is a discrete type. Return type:Boolean

class docplex.mp.vartype.ContinuousVarType

Bases: docplex.mp.vartype.VarType

This class models the continuous variable type and is not meant to be instantiated. Each model contains one instance of this type.

is_discrete()

Checks if this is a discrete type.

Returns:False because this type is not a discrete type. Return type:Boolean

class docplex.mp.vartype.IntegerVarType

Bases: docplex.mp.vartype.VarType

This class models the integer variable type and is not meant to be instantiated. Each models contains one instance of this type.

is_discrete()

Checks if this is a discrete type.

Returns:True as this is a discrete type. Return type:Boolean

class docplex.mp.vartype.SemiContinuousVarType

Bases: docplex.mp.vartype.VarType

This class models the semi-continuous variable type and is not meant to be instantiated.

default_lb

This property returns the default lower bound for the type.

is_discrete()

Checks if this is a discrete type.

Returns:False because this type is not a discrete type. Return type:Boolean

class docplex.mp.vartype.SemiIntegerVarType

Bases: docplex.mp.vartype.VarType

This class models the semi-integer variable type and is not meant to be instantiated.

default_lb

This property returns the default lower bound for the type.

is_discrete()

Checks if this is a discrete type.

Returns:True because this type is an integer type. Return type:Boolean

class docplex.mp.vartype.VarType

Bases: object

This abstract class is the parent class for all types of decision variables.

This class must never be instantiated. Specialized sub-classes are defined for each type of decision variable.

cplex_typecode

This property returns the CPLEX type code for this type. Possible values are:

• ‘B’ for binary type
• ‘I’ for integer type
• ‘C’ for continuous type
• ‘S’ for semicontinuous type
• ‘N’ for semiinteger type

Returns:a one-letter string.

default_lb

This property returns the default lower bound for the type.

default_ub

This property returns the default upper bound for the type.

is_discrete()

Checks if this is a discrete type.

Returns:True if the type is a discrete type. Return type:Boolean

short_name

This property returns a short name string for the type.

to_string()

Returns:A string representation of the type. Return type:string
