VQDResult

class VQDResult[source]

Bases: qiskit.algorithms.variational_algorithm.VariationalResult, qiskit.algorithms.eigen_solvers.eigen_solver.EigensolverResult

Pending deprecation: VQD Result.

The VQDResult class has been superseded by the qiskit.algorithms.eigensolvers.VQDResult class. This class will be deprecated in a future release and subsequently removed after that.

Methods
