qiskit.optimization.problems.Variable¶

class Variable(quadratic_program, name, lowerbound=0, upperbound=1e+20, vartype=<VarType.CONTINUOUS: 0>)[Quellcode]¶

Representation of a variable.

Creates a new Variable.

The variables is exposed by the top-level QuadraticProgram class in QuadraticProgram.variables. This constructor is not meant to be used externally.

Parameter

Verursacht

QiskitOptimizationError – if lowerbound is greater than upperbound.

__init__(quadratic_program, name, lowerbound=0, upperbound=1e+20, vartype=<VarType.CONTINUOUS: 0>)[Quellcode]¶

Creates a new Variable.

The variables is exposed by the top-level QuadraticProgram class in QuadraticProgram.variables. This constructor is not meant to be used externally.

Parameter

Verursacht

QiskitOptimizationError – if lowerbound is greater than upperbound.

Methods
