Variable#

class Variable(quadratic_program, name, lowerbound=0, upperbound=1e+20, vartype=VarType.CONTINUOUS)[source]#

Bases: QuadraticProgramElement

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.

প্যারামিটার:

  • quadratic_program (Any) -- The parent QuadraticProgram.

  • name (str) -- The variable name.

  • lowerbound (float | int) -- The variable lowerbound.

  • upperbound (float | int) -- The variable upperbound.

  • vartype (VarType) -- The variable type.

রেইজেস:

QiskitOptimizationError -- if lowerbound is greater than upperbound.
