Not sure how long I've been running my sim, but so far no bot could invade it successfully. The best attempt was by Preditor7, which came in, replicated to pretty high levels (~300 bots vs 50-60 of my evolved Carnatus) and then mysteriously died out in a typical "War of the Worlds" style (its population quickly crashed to 10-20 and then those died out pretty quickly too).

Is your sim very small?  Less than (or around) 100 bots?  The dynamics you describe remind me of stochastic dynamics of small populations. The rule of thumb for those is that any fitness differences that are < or ~= to 1/N are not important and behave as neutral alleles. And those get replaced rarely but rapidly due to chance.

Yes, actually.  My average population is 170 with the cancerous veggy spikes.  An median population is probably around a hundred.  Good to see the sim behaving like real life.

Peter:
What are in fact the species everybody has and the enviroment they live in.

I just have a sim with at the moment multiply3 with pretty normal F1 costs, exept for the fact everything is everytime rounded down (0.001 becomes 0)is it a bug or something), somehow the cost multiplier is going up as hell. Having a cost multiplier of 33 a normal shot cost 66, isn't that much. A stupid shooting bot just dies.

Trying to aim the population around 200(20%) the population is always higher and trigering the cost multiplier. Having mostly around 250 bots with pikes towards 300 and down to 180 or so.

What's happening in the other sims, I am interested.

Elite:
Currently running a sim on size 2 with non-evolving Bestia Mactabilis. Other bots occasionally teleport in, but nothing takes hold. Is anyone getting any Bestias arriving in they're sims? How do they do?

Preditor7 is a rather interesting one. For a mutated bot with incredibly mutated dna, it's scarily good at fighting and adapting. A few teleport in every so often, and they're usually quite good at holding my bots off for a while.

Internet mode is so fascinating!

EricL:
I generally have between three and five machines running mid sized fields and basically F1 league mode phsyics and costs with autocosts keeping the population at around 1000 bots each.  At the moment, Lionfish 1.4, Preditor 7 and multiply(peter) exist in all three of my currently running sims with varying populations.  In fact, the leader w.r.t. population is different in each one currently.  I try to leave at least three machines going all the time so I guess I host the bulk of Internet mode most of the time.  Pred7 has dominated over the past few days, but challengers have made him extint in at least one of the three sims multiple times.  But then a version will teleport in from another sim and win it back.  I think sim isloation effectively allows for speciation of mutating bots like Pred7.   The populations in differnet sims develop in differnet directions.  The Pred7 you encounter in one isn't necessarily the Pred7 you find in another.

Pred7 was a pretty complete battle bot in it's initial unmutated form with a wide array of attacks and counter attacks.  It doesn't surprise me too much that the mutated version(s) are highly effective.  Perhaps competition in internet mode - with other Pred7 strains and other species - provides for stablizing selection which preserves that effectiness even after 500 cumulative mutations...

I see them come in occasionally, but they don't last.  Currently none in any of my three sims though the pop graphs show they have come in...
