Basic Usage

This example shows how to solve a basic qubo using Dirac-3. The solver setup requires that environment variables are configured for connection.

import numpy as np
from eqc_models.solvers import Dirac3CloudSolver
from eqc_models.base import QuadraticModel
J = np.array([[0, 1], [1, 0]])
C = -1*np.ones((2,), dtype=np.int64)
model = QuadraticModel(C, J)
model.upper_bound = np.ones((2,), dtype=np.int64)
# this will print the quadratic model in QUBO form
print(model.qubo.Q)
solver = Dirac3CloudSolver()
response = solver.solve(model, num_samples=5, relaxation_schedule=1)
for sol in response["results"]["solutions"]:
    print(sol)
