摘要: Abstract An exact, nonlocal algorithm for Monte Carlo simulation of theories with dynamical fermions is proposed. The based on obtaining the new configuration U from old one by solving equation M( )η=ωM(U)η , where M fermionic operator, η random Gaussian vector, and ω real number close to unity. This can be used acceleration current simulations in Grassmann variables. A first test was done SU(3) QCD purely term action.
