Fast optimization by Demon Algorithms

Wood, Ian A. & Downs, Tom (1998) Fast optimization by Demon Algorithms. In Downs, Tom, Frean, Marcus, & Gallagher, Marcus (Eds.) Australian Conference on Neural Networks 1998, February 11-13, University of Queensland, Brisbane, QLD, Australia.


We introduce four new general optimization algorithms based on the `demon' algorithm from statistical physics and the simulated annealing (SA) optimization method. These algorithms use a computationally simpler acceptance function, but can use any SA annealing schedule or move generation function. Computation per trial is significantly reduced. The algorithms are tested on traveling salesman problems including Grotschel's 442-city problem and the results are comparable to those produced using SA. Applications to the Boltzmann machine are considered.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
