On the contrary: Axelrod (1984) or Axelrod and Hamilton(1981) is
referenced in most, if not all, of Nowak's work on the evolution of
cooperation in the Iterated Prisoners' Dilemma(IPD) and can be
viewed as
an extension of Axelrod's work. Nowak has pointed out that mistake-
free
play is an artifact of Axelrod's tournament. Nowak claims that when
mistakes such as a "trembling hand," which is an incorrect
implementation
of one's own strategy, or a "fuzzy mind," which is a
misinterpretation of
one's partner's strategy, are introduced Tit-For-Tat does no better
than a
mixed strategy that cooperates or defects at the flip of a coin.
Therefore, Nowak has reduced TFT to "the pivot rather than the aim
of an
evolution towards cooperation" (Nowak and Sigmund, 1992). Nowak
instead
maintains that natural selection favors a strategy called win-stay,
lose-shift or Pavlov. Pavlov cooperates only if the response of both
players was the same in the previous round. Pavlov's response in the
first round is considered to be negligible because it is tested in an
infinitely repeated Prisoners' Dilemma.
In addition, the following link is to one of Nowak's lectures on the
evolution of cooperation:
http://athome.harvard.edu/programs/evd/index.html.
And, Nowak's most recent book Evolutionary Dynamics
(http://www.ped.fas.harvard.edu/people/faculty/Books.html) gives a
fairly
detailed overview of his areas of research: cooperation,
evolutionary game
theory, evolutionary graph theory, and their applications to virus,
cancer
and disease. I would be happy to lend it to anyone at FriAM.

Here's what I don't quite get (and would be interested in knowing
more about from those who understand priority): I read and was deeply
influenced by "The Evolution of Cooperation" by Robert Axelrod,
shortly after its 1984 publication. Axelrod ran a round-robin
Prisoners Dilemma tournament, which yielded strategies he called "tit
for tat" and "tit for two tats" as victors (depending on the
conditions), and explored such matters (if memory serves) as
recognition/reciprocity and recurrent contacts.
Why is there no mention of this in the Nowak stuff, which sounds
oddly familiar to my non-technical ear?

Looking at his selected list of publications (http://
www.ped.fas.harvard.edu/people/faculty/select_list.html) I'm very
interested in his work.
There are enough pdf's of papers linked to the publication list to
delay any further reaction by a few months.
Nick started us discussing this thread:
Hauert C, A Traulsen, H Brandt, MA Nowak, K Sigmund (2007). Via
freedom to coercion: the emergence of costly punishment. Science
316: 1905-1907
just last week in the context of road rage.

Though this might interest some on the list; I'd be interested to
hear any reactions to Nowak's work:
SCIENTIST AT WORK | MARTIN NOWAK
In Games, an Insight Into the Rules of Evolution
By CARL ZIMMER
Martin Nowak's projects may seem randomly scattered across the
sciences but they share an underlying theme: cooperation.
