Abstract :
This paper compares Software Breeding, a new approach for improving the reliability of multiversion software, with Community Error Recovery by mathematical models of the reliability of the multiversion software by these. The following results were obtained: (1) the reliability of the Software Breeding increases when the number of modules of the multiversion software increases, (2) the multiversion software by Software Breeding is more reliable than by the Community Error Recovery unless the reliability of a program version is low and (3) the Software Breeding can improve the reliability of multiversion software more easily than the Community Error Recovery since the Software Breeding does not need any additional routine which must have very high reliability except for the driver module
