QAOAType¶

class QAOAType¶

ベースクラス: Enum

Selects the QAOA circuit construction strategy.

Pass this as QAOA.Parameters.qaoa_type to control which implementation is used when building the QAOA ansatz.

Attributes

`AUTO`	Automatically choose the best implementation based on the problem structure.
`AUTO_QUADRATIC`	Like `AUTO` but restricts the objective to quadratic form.
`ORIGINAL`	Standard QAOA for unconstrained Ising problems.
`ORIGINAL_QUADRATIC`	Like `ORIGINAL` but restricts the objective to quadratic form.
`NHOT`	QAOA that preserves equal to constraints throughout the circuit, keeping the quantum state in the feasible subspace.
`NHOT_QUADRATIC`	Like `NHOT` but restricts the objective to quadratic form.

classmethod __contains__(value)¶

Return True if value is in cls.

value is in cls if: 1) value is a member of cls, or 2) value is the value of one of the cls's members. 3) value is a pseudo-member (flags)

classmethod __getitem__(name)¶: Return the member matching name.

classmethod __iter__()¶: Return members in definition order.

classmethod __len__()¶: Return the number of members (no aliases)
