    The Grand Challenge in Non-Classical Computation: International Workshop.
  • Conference start date:

  • Keywords:
    genetic algorithms, genetic programming
  • Addresses:
    York, UK.
  • Notes:
    Fitness distributions (landscapes) of programs tend to a limit as they get bigger. Markov minorization gives upper bounds ((15.3 + 2.30 m)/log(I)) on the length of program run on random or average computing devices. I is the size of the instruction set and m size of output register. Almost all programs are constants. Convergence is exponential with 90% of programs of length 1.6 n 2**N yielding constants (n=size input register and size of memory=N). This is supported by experiment.
