Example

from amplify import BinarySymbolGenerator
from amplify.client import FixstarsClient

gen = BinarySymbolGenerator()
q = gen.array(3)
f = 2 * q[0] * q[1] - q[0] - q[2] + 1  # BinaryPoly type input model

client = FixstarsClient()
client.token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
client.parameters.timeout = 1000  # timeout 1 second

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