# docplex.mp.vartype module¶

class docplex.mp.vartype.BinaryVarType[source]

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

is_discrete()[source]

Checks if this is a discrete type.

Returns: True as this is a discrete type. Boolean
class docplex.mp.vartype.ContinuousVarType[source]

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

is_discrete()[source]

Checks if this is a discrete type.

Returns: False because this type is not a discrete type. Boolean
class docplex.mp.vartype.IntegerVarType[source]

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

is_discrete()[source]

Checks if this is a discrete type.

Returns: True as this is a discrete type. Boolean
class docplex.mp.vartype.SemiContinuousVarType[source]

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()[source]

Checks if this is a discrete type.

Returns: False because this type is not a discrete type. Boolean
class docplex.mp.vartype.SemiIntegerVarType[source]

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()[source]

Checks if this is a discrete type.

Returns: True because this type is an integer type. Boolean
class docplex.mp.vartype.VarType[source]

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()[source]

Checks if this is a discrete type.

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

This property returns a short name string for the type.

to_string()[source]
Returns: A string representation of the type. string
