Cluster dynamics for randomly frustrated systems with finite connectivity

Abstract: In simulations of some infinite range spin glass systems with finite connectivity, it is found that for any resonable computational time, the saturated energy per spin that is achieved by a cluster algorithm is lowered in comparison to that achieved by Metropolis dynamics. The gap between the average energies obtained from these two dynamics is robust with respect to variations of the annealing schedule. For some probability distribution of the interactions the ground state energy is calculated analytically wi… Show more

“…On φ z graphs we replace 2 → z − 1, which is still in accordance with equs. (3,4). As all even bifurcation points are independent of p, we predict the p independence of the spin glass transition point, as in the more standard approaches.…”

“…[21] in alternation with standard Swendsen-Wang [22] cluster updates on each of the replicas. The additional Swendsen-Wang updates are very efficient close to percolation and speed up the simulation considerably [23]. This is an important issue because close to percolation we encounter noticeable finite-size effects, and therefore relatively large lattices have to be simulated to see a good signal for a SG transition below p * .…”

“…In the context of manipulating creative concepts, this translates in very long times for producing really innovative and successful ideas. The usual solution in the context of statistical mechanics is the identication of eective collective degrees of freedom and devising algorithms which act directly in terms of these macroscopic degrees of freedom (macros 4 ). Such procedures replace the slow dynamics based on random walk by a dynamics relying on macroscopic steps.…”

“…T h us we w ould reproduce in the NPD context the capability of the cluster-multiscale algorithms to transcend critical slowing down. 4 In order to apply such techniques, one has to ascertain that the system is to a good approximation isolated from external changes and that its global dynamics can be expressed in terms of discrete degrees of freedom. These requirements might seem problematic in the context of marketable products:…”
