Geometric allocation approach to accelerating directed worm algorithm

چکیده
The worm algorithm is a versatile technique in the Markov chain Monte Carlo method for both classical and quantum systems. substantially alleviates critical slowing down reduces dynamic exponents of various It crucial to improve push boundary physical We here propose directed that significantly improves computational efficiency. use geometric allocation approach optimize scattering process: backscattering averted, forward favored. Our successfully enhances diffusivity head (kink), which evident probability distribution relative position two kinks. Performance improvement demonstrated Ising model at temperature by measurement exponential autocorrelation times asymptotic variances. present update approximately 25 as efficient conventional simple cubic lattice model. Surprisingly, our even more than Wolff cluster algorithm, one best algorithms. estimate exponent be $z \approx 0.27$ update. algorithms produce different integrated time magnetic susceptibility estimator but same variance. also discuss how quantify efficiency method. can applied wide range systems, such $| \phi |^4$ model, Potts O($n$) loop QCD.

15 صفحه اولMultiprocessor Document Allocation: A Genetic Algorithm Approach
We formally define the Multiprocessor Document Allocation Problem (MDAP) and prove it to be computationally intractable (NP Complete). Once it is shown that MDAP is NP Complete, we describe a document allocation algorithm based on genetic algorithms. This algorithm assumes that the documents are clustered using any one of the many clustering techniques. We later show that our allocation algorit...
متن کاملA philosophical Approach to the Allocation or Aggregation of Geography
Introduction Geography first started with simple writing. But today, this science has gained a lot of potentials and with its technical tools which has at hand, has new specialized trends and is training new experts and specialists. Hence, in the present age, especially in Iran, geography is referred to as (interdisciplinary science), because it both studies natural sciences and human sciences...
متن کاملOptimal Resource Allocation for Network Protection: A Geometric Programming Approach
We study the problem of containing spreading processes in arbitrary directed networks by distributing protection resources throughout the nodes of the network. We consider two types of protection resources are available: (i) Preventive resources able to defend nodes against the spreading (such as vaccines in a viral infection process), and (ii) corrective resources able to neutralize the spread...
