In this article we introduce a hybrid simulation method termed MC\u2010SD which mixes Monte Carlo (MC) and stochastic dynamics (SD). This new method generates a canonical ensemble via alternating MC and SD steps and combines the local exploration strengths of dynamics with the barrier\u2010crossing ability of large\u2010step Monte Carlo. Using calculations on double\u2010well potentials and long simulations (10<jats:sup>8<\/jats:sup> steps of MC and 1 \u03bcs of SD) of the simple, conformationally flexible molecule <jats:italic>n<\/jats:italic>\u2010pentane, we find that MC\u2010SD simulations converage faster than either MC or SD alone and generate ensembles which are equivalent to those created by classical MC or SD. Using pure SD at 300 K, the conformational populations of <jats:italic>n<\/jats:italic>\u2010pentane are shown to be poorly converged even after a full microsecond of simulation. \u00a9 1994 by John Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/jcc.540151111","type":"journal-article","created":{"date-parts":[[2005,1,2]],"date-time":"2005-01-02T00:57:39Z","timestamp":1104627459000},"page":"1302-1310","source":"Crossref","is-referenced-by-count":160,"title":["A rapidly convergent simulation method: Mixed Monte Carlo\/stochastic dynamics"],"prefix":"10.1002","volume":"15","author":[{"given":"Frank","family":"Guarnieri","sequence":"first","affiliation":[]},{"given":"W.
