Pattern
Recognition Triple Version Algorithm (PRTVA) is an interpretation, in the
field of Pattern Recognition, of N-Version Programming (NVP). N-Version Programming (NVP), also known as multi-version
programming or multiple-version
dissimilar software, is a method or process in software engineering where
multiple functionally equivalent programs are independently generated from
the same initial specifications. The concept of N-Version Programming was introduced in 1977 by
Liming Chen and Algirdas Avizienis
with the central conjecture that the independence of programming efforts will
greatly reduce the probability of identical software faults occurring in two
or more versions of the program. The aim of NVP is to improve the reliability
of software operation by building in fault tolerance or redundancy. The
real equivalence of PRTVA with NVP exists when PRTVA is applied in FLAT PROBABILISTIC
MODE. In reality, PRTVA does not consider all algorithms with the same
priority. PRTVA evaluates the result of the algorithms in a hierarchical way
based on the tolerance of the Norm that they use to calculate the vector
distances (Hierarchy of Nom Selectivity). |
