J-walking

While J-walking has proved to be useful for many applications, the need for a series of large external distributions limits its application to many-body systems having modest numbers of particles. The needed configurations for J-walking can require a prohibitively large portion of both computer memory and disk space. In the next section we describe another approach that obviates the need for external distributions.

Many additional search methods have been devised in addition to the basic three just discussed. A few of them are outhned below. Note that whereas some methods, such as parallel tempering and J-walking, are improved or speciahzed versions of the basic tech-... 

In J-walking [20] the periodic MC trial probability for a simulation at temperature T is taken to be a Boltzmann distribution at a high temperature, Tj ( 3j = IkTj), The jumping temperature, 7), is sufficiently high that the Metropolois walk can be assumed to be ergodic. This results in the acceptance probability.
