The Evolution of Random Number Generation in MUVES

Authors: Joseph C Collins
Date/Pages: January 2017; 50 pages
Abstract: The evolution of random number generation in MUVES proceeds from a short-period low-resolution single-threaded legacy implementation with questionable numerical and statistical properties. The development of the modern system is traced through software change requests, resulting in a random number generator that overcomes all shortcomings of the legacy system. This report traces the history of random number generation in MUVES, including the mathematical basis and statistical justification for algorithms used in the code. The working code provided produces results identical to the current implementation. These theoretical and practical details enable the reader to understand the algorithms and ensure that future enhancements to the production code preserve the integrity of the system.
