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(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.

パラメータ

values (numpy.ndarray) – array of values.

戻り値

operator for the Hamiltonian and a constant shift for the obj function.

戻り値の型

tuple(WeightedPauliOperator, float)

partition_value(x, number_list)

Compute the value of a partition.

パラメータ

• x (numpy.ndarray) – binary string as numpy array.

• number_list (numpy.ndarray) – list of numbers in the instance.

戻り値

difference squared between the two sides of the number

partition.

戻り値の型

float
