We study the efficiency of an improved multiboson algorithm with two flavors of Wilson fermions in a realistic physical situation (beta = 5.60,k = 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.

Abstract

We study the efficiency of an improved multiboson algorithm with two flavors of Wilson fermions in a realistic physical situation (beta = 5.60,k = 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.
