Good parameters please! 

Firs of all: How about something like that of the Golem project where a
creature from one gene pool could emigrate to that of another computer? Sort
of a distributed computing system. The idea is very simple: If the new
creature in the gene pool have superior qualities, it would "take over" the
population, which is good since then more computers will evolve it. Or maybe
it just have good qualities when cross-over with the current breeds excist.

Framstick could create a set of 2-3 "standard" parameters with different
Objectives, and emigration could then only occur between computers that used
the same parameter-set.

So to the real question:
Hi, I'm looking for a good set of parameters. Ideally I want all aspects
involved = death, food, collission (not water).

With food:
Problems are the same as ever - i.e. the creatures will get so big that they
can just lay there and reach all food balls because of their size. Velocity
is "on" so they have to move some, but...

Velocity:
Too often the gene pool will lose its diversication at once if one creature
picks up velocity, if it just goes round and round.

Also, I can't find the parameters that controlled how much energy the
muscles used. This is an important factor to prevent those huge creatures.

Anyone that has a set of simulator parameters that actually works? Should be
able to start from scracth (X) and run for 1 year.

A question about good parameters is always a good question :-)

...but what is your goal, or the purpose of those parameters?

Size (number of elements) is more basic one.

...and what do you expect during that one year?

Convergence?
Divergence?
Stability?
Extinction?

Using "standard.expdef", you usually expect some kind
of optimization, so: convergence and stability at last
(this is the main purpose of that experiment definition).

For more realistic evolution, where you have to cope with
another problems - like unstability and extinction - a new
experiment definition might be better.

I have found that these problems all have a single simple solution: define
fitness solely in terms of horizontal distance. This will keep the
creatures moving, and they will eventually head toward food to keep from
starving to death and thus go even further distances in their extended
lifetimes.

Try a world size of 50, with 4 to 10 food balls with their energy level set
to maximum.
