We study the efficiency of an improved multiboson algorithm with two flavors of Wilson fermions in a realistic physical situation (β=5.60,κ=0.156 on a 163X24 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. ©2000 The American Physical Society.
