摘要
We study the efficiency of an improved multiboson algorithm with two flavors of Wilson fermions in a realistic physical situation (beta = 5.60,kappa = 0.156 on a 16(3) x 24 lattice). The performance of this exact algorithm is compared with that of a state-of-the-art HMC algorithm: a considerable improvement is obtained for the plaquette auto-correlation time, while the two algorithms appear similarly efficient at decorrelating the topological charge.
