Simulation in exponential families
Philippe Barbe, Michel Broniatowski
Pages: 203-223
DOI: 10.1145/347823.347824
An acceptance-rejection algorithm for the simulation of random variables in statistical exponential families is described. This algorithm does not require any prior knowledge of the family, except sufficient stati stics and the value of the...

Efficient optimistic parallel simulations using reverse computation
Christopher D. Carothers, Kalyan S. Perumalla, Richard M. Fujimoto
Pages: 224-253
DOI: 10.1145/347823.347828
In optimistic parallel simulations, state-saving techniques have traditionally been used to realize rollback. In this article, we propose reverse computation as an alternative approach, and compare its execution performance...

Redundancy in model specifications for discrete event simulation
Richard E. Nance, C. Michael Overstreet, Ernest H. Page
Pages: 254-281
DOI: 10.1145/347823.347831
Although redundancy in model specification generally has negative connotations, we offer arguments for revising those convictions. Defining “representational redundancy” as the inclusion of any symbols not required to fulfill the...

Getting rid of correlations among pseudorandom numbers: discarding versus tempering
Stefan Wegenkittl, Makoto Matsumoto
Pages: 282-294
DOI: 10.1145/347823.347835
We consider the impact of discarding and tempering on modern huge period high speed linear generators, and illustrate how a simple strategy yields unexpected &mdashh; and unwanted — success in a fair coin gambling which is simulated by a...
