From the Ewert, Dembski, and Marks paper on Avida:

If the fitness of the organism
does not decrease, we keep the mutation and repeat the
iteration. If the fitness does increase, the mutation is
discarded and the process repeated.


What is this, the almost completely neutral evolution strategy?

It's the middle of the night, and maybe my eyes just are too glazed over, but can anybody else see why all the R strategy values for successes in Table III are the same, 353?

I don't know, but I did notice that under Table III
   
Quote
ALL SIMULATIONS, EXCEPT Q, HAVE 353 RUNS

with the same values for the random strategies - but this does not match Marks' comparable slide


Which now gives avida strategy values in place of the random strategy values cited in the paper. Huh? What is going on?

Which came first: the shimmy, or the hip?
