QAOA Parameters

BasicQAOAParams ¶

Bases: BaseModel

Individual QAOA Parameters.

Parameters betas and gammas need to be of same size.

Attributes:

Name	Type	Description
`betas`	`list[float]`	List of beta parameters for the mixer layers in QAOA.
`gammas`	`list[float]`	List of gamma parameters for the cost layers in QAOA.

betas: list[float] = Field(
    description="List of beta parameters for the mixer layers in QAOA."
)

gammas: list[float] = Field(
    description="List of gamma parameters for the cost layers in QAOA."
)

reps: int

Returns the number of layers.

Bases: BaseModel

Linear QAOA Parameters.

Linearly decreasing beta parameters from delta_beta to zero. Linearly growing paramters from zero to delta_gamma.

Attributes:

Name	Type	Description
`delta_beta`	`float`	Parameter scaling for the beta paramters for the mixer layers in QAOA.
`delta_gamma`	`float`	Parameters scaling for the gamma parameters for the cost layers in QAOA.

delta_beta: float = Field(
    description="Parameter scaling for the beta paramters for the mixer layers in QAOA."
)

delta_gamma: float = Field(
    description="Parameters scaling for the gamma parameters for the cost layers in QAOA."
)

Bases: BaseModel

Uniform random QAOA Parameter within predefined value ranges.

Attributes:

Name	Type	Description
`seed`	`int \| None`	Seed for random number generator.
`beta_range`	`tuple[float, float]`	Value range for uniform random beta parameters (mixer layer).
`gamma_range`	`tuple[float, float]`	Value range for uniform random gamma parameters (cost layer).

beta_range: tuple[float, float] = Field(
    default=(0, 2 * pi),
    description="Value range for uniform random beta parameters (mixer layer).",
)

gamma_range: tuple[float, float] = Field(
    default=(0, 2 * pi),
    description="Value range for uniform random gamma parameters (cost layer).",
)

seed: int | None = Field(
    default=None, description="Seed for random number generator."
)
