This "solve-a-problem" perspective Ian mentions (and which appears to be
a necessary consideration in evaluating the success of genetic algorithm
research) sort of picks at the edge of my mind. Our human perspective
assumes (as also suggested by our Scriptures) that we and our kindred
life forms are the single culmination (and particular objective) of
God's Creation. My question is whether this is a correct assumption.
[There may be something moot here!] It would seem to me that it might
be AN outcome of significance, but do we really have enough insight into
the mind of God to know that it is We are?) THE solution to THE problem
presumably being addressed in Creation?
It is the remarkable thing about evolution, in whatever form it takes,
that it "explores". It arguably solves local problems (local in both
spatial and temporal senses), but its ultimate course(s) and
"accomplishments" are potentially many (and may or may not be under the
direct influence of God, depending upon ...well, how He elects - or not
- to interact with Creation at any given time. This process-determined
(as opposed to direction-determined) is of course a sticking point that
bothers so many who struggle with the whole concept of evolution. Our
human sense (for some, at least) is that Creation was put into place in
this particular form so that we and our kind would ultimately "happen".
Arguments have certainly been offered that Creation was designed so that
the emergence of life in some form, somewhere was an imperative. There
of course are many ways that God could cause His Creation to move in
accordance with His intent with little or even no continuing active
agency (front-loaded design, rule-and-initial-conditions "attraction" a
la chaos theory, etc.). I speak of agency here in the sense of activity
in the limited context of the physical world.
But even in our limited human thinking and perspectives, we can see that
God could act more directly and immediately (flash-boom instantaneous
creation and essentially static result) if creating and having humans
and all their related kinds about. That isn't the way we understand our
physical world to function. Why a flow of time? Why bother with death
and selection and all that stuff if there were a single focal "problem"
and "solution"? And why such an immense universe of places and things
and conditions?
But the the universe IS immense, beyond human ken, with stars and solar
systems beyond our ability to count or resolve them with eye or
instrument. And, the dynamics of the created universe proceed on
essentially numberless stages. For what purpose if humans and
human-related kinds of life were the sole objective?
Here's my point, I can't help but wonder if the "space" being explored
by this dynamic Creation of which we are a part does not have room for
many "solutions", and that "solutions" may not even be the proper way to
conceptualize the endpoint(s) of the operation of the grand universe,
since it implies counterpart "problems". I question the "problem" part.
It would seem to me that the "exploratory" nature of evolutionary
processes might not be about solving a problem in any conventional
sense. Our conceptualization of "problem" could easily fall a tad short
of how transcendent God ...uh...conceptualizes one. But is there a tiny
clue from his Creation? It appears that the "exploratory" character of
evolutionary processes is more about seeing where it goes and what's
there at the end of the day, rather than a point solution to a
particular problem.
That of course poses the real (and I'm sure, well recognized) difficulty
in the creation of an analogous genetic algorithm and determining its
success or failure, because the criteria for success needs to be a
predetermined component of the algorithmic evaluation. But that's (of
apparent necessity) a very closed definition of "success". I'm not sure
the magnitude of the universe, with its huge spectrum of places, and
conditions, and times, and unthinkable numbers of possible evolutionary
paths is likely to be linked to any given single definition of
"success", nor - I would speculate - is it likely that our concept of a
definition of "problem" even apropos.
Just a thought...or so it seemeth to me. JimA
