Abstract :
An experiment in which relatively low-quality programs were run in an N-version mode on a microcomputer-based network specifically developed to support N-version programming is described. A 20% reduction in average failure probability over individual versions was noted, but at a substantial overhead in execution time. Heuristics for calculating failure rates and for voting in an N-version mode were developed to deal with the iterative nature of the applications problem.<>
