Abstract: We present a specific algorithm that generally satisfies the balancecondition without imposing the detailed balance in the Markov chain MonteCarlo. In our algorithm, the average rejection rate is minimized, and evenreduced to zero in many relevant cases. The absence of the detailed balancealso introduces a net stochastic flow in a configuration space, which furtherboosts up the convergence. We demonstrate that the autocorrelation time of thePotts model becomes more than 6 times shorter than that by the conventionalMetropolis algorithm. Based on the same concept, a bounce-free worm algorithmfor generic quantum spin models is formulated as well.
