Quick Start

pip install admiral-solver

from admiral import Solver
import numpy as np

solver = Solver(api_key="adm_sk_...")
Q = np.array([[-5, 2, 4], [0, -3, 1], [0, 0, -8]])
result = solver.solve_qubo(Q, timeout=30)
print(result.energy)     # -13.0
print(result.solution)   # [1, 0, 1]

Local mode (no server):

from admiral import LocalSolver
result = LocalSolver().solve_qubo(Q, solver="tabu", seed=42)
