Example

from amplify import BinarySymbolGenerator
from amplify.client import ToshibaClient

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

client = ToshibaClient()
client.url = "http://xx.xxx.xxx.xx:xxxx/"
client.parameters.timeout = 1  # 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]
['energy = -1.0, q = [1. 0. 1.]']
property solver
