# EvolutionResult

*class* `qiskit.algorithms.EvolutionResult(evolved_state, aux_ops_evaluated=None)`

[GitHub](https://github.com/qiskit/qiskit/tree/stable/0.46/qiskit/algorithms/evolvers/evolution_result.py)

Bases: `AlgorithmResult`

Deprecated: Class for holding evolution result.

The EvolutionResult class has been superseded by the `qiskit.algorithms.time_evolvers.TimeEvolutionResult` class. This class will be deprecated in a future release and subsequently removed after that.

> **Deprecated since version 0.24.0**
>
> The class `qiskit.algorithms.evolvers.evolution_result.EvolutionResult` is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. Instead, use the class `qiskit.algorithms.time_evolvers.TimeEvolutionResult`. See [https://qisk.it/algo\_migration](https://qisk.it/algo_migration) for a migration guide.

**Parameters**

- **evolved\_state** ([*StateFn*](/docs/api/qiskit/0.46/qiskit.opflow.state_fns.StateFn "qiskit.opflow.state_fns.StateFn")  *|*[*QuantumCircuit*](/docs/api/qiskit/0.46/qiskit.circuit.QuantumCircuit "qiskit.circuit.QuantumCircuit")  *|*[*OperatorBase*](/docs/api/qiskit/0.46/qiskit.opflow.OperatorBase "qiskit.opflow.OperatorBase")) – An evolved quantum state.
- **aux\_ops\_evaluated** (*ListOrDict\[*[*tuple*](https://docs.python.org/3/library/stdtypes.html#tuple)*\[*[*complex*](https://docs.python.org/3/library/functions.html#complex)*,* [*complex*](https://docs.python.org/3/library/functions.html#complex)*]] | None*) – Optional list of observables for which expected values on an evolved state are calculated. These values are in fact tuples formatted as (mean, standard deviation).

## Methods

### combine

`combine(result)`

Any property from the argument that exists in the receiver is updated. :param result: Argument result with properties to be set.

**Raises**

[**TypeError**](https://docs.python.org/3/library/exceptions.html#TypeError) – Argument is None
