### get\_solver
<Function id="qiskit.chemistry.algorithms.MinimumEigensolverFactory.get_solver" signature="MinimumEigensolverFactory.get_solver(transformation)" modifiers="abstract">
Returns a minimum eigensolver, based on the qubit operator transformation.
**Parameters**
**transformation** (`Transformation`) The qubit operator transformation.
**Return type**
`MinimumEigensolver`
**Returns**
A minimum eigensolver suitable to compute the ground state of the molecule transformed by `transformation`.

### supports\_aux\_operators
<Function id="qiskit.chemistry.algorithms.MinimumEigensolverFactory.supports_aux_operators" signature="MinimumEigensolverFactory.supports_aux_operators()" modifiers="abstract">
Returns whether the eigensolver generated by this factory supports auxiliary operators.
**Return type**
`bool`
</Function>
