# amplify.client.FujitsuDASolverClientParameters¶

class FujitsuDASolverClientParameters

A class that handles the parameters of FujitsuDASolverClient.

__init__(*args, **kwargs)

Methods

 __init__(*args, **kwargs)

Attributes

 guidance_config Specifies the initial values of variables. number_iterations Number of searchs in one annealing. number_runs Number of repeats of annealing. solution_mode Specifies how solutions are returned.
property guidance_config

Specifies the initial values of variables. The initial configuration of the variables are expressed in terms of a dictionary. The key is the index of a variable in the string form, and the corresponding value is the initial value of the variable expressed as True or False.

Type

dict

Example

from amplify import BinarySymbolGenerator
from amplify.client import FujitsuDASolverClient

gen = BinarySymbolGenerator()
q = gen.array(3)
f = 2 * q[0] * q[1] - q[0] - q[2] + 1

client = FujitsuDASolverClient()
client.token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
client.parameters.number_iterations = 1000000
client.parameters.guidance_config = {"0": True, "2": False}

result = client.solve(f)

>>> f
2 q_0 q_1 - q_0 - q_2 + 1
>>> print([f"energy = {s.energy}, q = {q.decode(s.values)}" for s in result])
['energy = -1.0, q = [1. 0. 1.]',
'energy = 1.0, q = [0. 0. 0.]']


Modifying each element of guidance_config by direct reference is not supported. If you need to replace one or more elements, the entire dictionary needs to be redefined.

from amplify.client import FujitsuDASolverClient

client = FujitsuDASolverClient(token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
client.parameters.guidance_config = {"0": True, "1": True}

>>> client.parameters.guidance_config
{'1': True, '0': True}
>>> client.parameters.guidance_config["0"] = False # Dictionary elements cannot be replaced by direct reference.
>>> client.parameters.guidance_config
{'1': True, '0': True}
>>> client.parameters.guidance_config= {"0": False, "1": False}  # Redefition of the entire dictionary can replace dictionary elements.
>>> client.parameters.guidance_config
{'1': False, '0': False}

property number_iterations

Number of searchs in one annealing. Specified by an integer greater than or equal to 1.

Type

int

property number_runs

Number of repeats of annealing. Specified by an integer greater than or equal to 1. If not specified, set to 100 as the default. Recommended to set it to a value that is a multiple of 20 and is such that number_runs$$\times$$number_iterations being greater than or equal to 100,000.

Type

int

property solution_mode

Specifies how solutions are returned. Can be set to "COMPLETE" or "QUICK". "COMPLETE" is set as the default if no value is specified.

• COMPLETE: Returns all results obtained by the number of annealing specified by number_runs, but combines the same results into one and returns with the total number of occurrence as frequency.

• QUICK: Returns one result with the lowerst energy.

Type

str
