Abstract
N-version programming has long been mooted as a method of improving software reliability. Earlier studies, which generated apparently discouraging results, offered pessimistic prognostications for this general strategy. However, further study of the problem has both refined the evaluation procedure and revealed new opportunities for improvement. In particular, exploitation of methodological diversity has proved to be productive. In this paper, we continue such studies by introducing a methodological extreme, an inductive computing technology, neural computing, to extend an earlier study of Modula2 and Prolog versions of the Launch Interceptor problem. In addition, we examine several diversity measures which are presented as more reliable indicators of potential reliability enhancement than the earlier measures of independence of failure and, subsequently, of probability of two-version joint failure. We also examine several strategies for diversity exploitation in multiversio...
