qiskit.optimization.applications.ising.partition
Generate Number Partitioning (Partition) instances, and convert them into a Hamiltonian given as a Pauli list.
Functions
get_operator(values) | Construct the Hamiltonian for a given Partition instance. |
partition_value(x, number_list) | Compute the value of a partition. |
get_operator
get_operator(values)
Construct the Hamiltonian for a given Partition instance.
Given a list of numbers for the Number Partitioning problem, we construct the Hamiltonian described as a list of Pauli gates.
Parameters
values (numpy.ndarray) – array of values.
Returns
operator for the Hamiltonian and a constant shift for the obj function.
Return type
tuple(WeightedPauliOperator, float)
partition_value
partition_value(x, number_list)
Compute the value of a partition.
Parameters
- x (numpy.ndarray) – binary string as numpy array.
- number_list (numpy.ndarray) – list of numbers in the instance.
Returns
difference squared between the two sides of the number
partition.
Return type
float
