Alga_Minimalis normally reproduces asexually.  Did you modify it to reproduce sexually?  I tried a similar sim years ago but that was before sexual reproduction.  I would think your bigger problem is keeping the prey from taking in predator DNA and becoming a photosynthetic predator, which would cause a lot more problems.

Either way, I don't have any off hand ideas.  We were talking about a minimum similarity measure with sexual reproduction to prevent vastly dissimilar species from sexually reproducing but I don't know if it was implemented.

I wouldn't worry too much about the cannibal predator species producing dumb babies from time to time.  The energy loss from producing a child then eating it aren't as high in Darwinbots as in the real world.

Newbie / Sexual Reproduction Issue

Hi everyone :)

I'm new to posting here, but I've been using DB, and browsing the forum, for the last couple of months. I'm currently trying to set up a basic predator-prey system using modified versions of the Animal_Minimalis_Connubialis. The idea is to have two populations of mobile robots- one population serving as predator, one as prey-  with repopulating Alga_Minimalis as food for the prey organisms. The issue I have been encountering is that the predators, who are necessarily more sparse and have slower breeding times, keep getting impregnated by the prey. This leads to offspring that are ostensibly predator robots, but act like the prey. This problem is self-solving to a certain point, as the predators often eat these offspring, but it wastes the resources of the parent organisms and alters the overall dynamic to an unacceptable degree. I am wondering if anyone has a good technique for avoiding this, short of making one species asexual. I have already altered the DNA of both organisms so that they should not seek to breed with each other, and the prey has been designed to flee from the predators, but I think that the predator robots are getting hit by stray sperm shots when they get too close to the prey while they are having their reproduction orgies lol

Thanks for any help. And my apologies if this question has been asked before. I checked through older threads but didn't see anything on this topic

There is still not much other good stuff out there, one reason I am still occasionally  checking for darwinbots3 ;P.  Sometimes I get some idea to make  my own game but then hit some snatch in the abstract mechanics or simple my programming skills.

offtopic: I recently considered that instant digestion time might be one of the reason Evo simulations are so instable in DB. I mean nature has so much organic material lying around and it often takes very long to recycle it, some thinks even have to decay first before beeing consumable. I think this stabilizes the food provision and slows life down enough to become isolated and such diverse.

If you're in to the scripting aspect, there's screeps.  I haven't played it but it's relatively well reviewed.  Personally I like programming games but it always feels like I should just be doing actual programming.

If you're in to the evolution aspect, I don't know of very much new, to be honest.  My impression is that most of that creative energy is currently doing neural net stuff, since that's super en vogue right now.  So any artificial life simulations of depth are from 10+ years ago.

But I'd love to hear I'm wrong! :)

I like darwinbots, but I would like to know if there are good alternatives do DB outthere...

Anyone is doing different stuff??

Was stuff remastered over the last couple of years btw? I think that'd be awesome.

Nothing at the moment.  I'm a bit stuck on the fluid model I'm using.

I had a problem with the fluid velocity becoming infinite far away from the bot.  I found this article which discusses the problem and provides a simple solution.  Now I need to find the forces the fluid puts on the bot and vice versa, which shouldn't be too hard but I've run out of steam.

What's new regarding darwinbots?     There's been very little

There's been very little.  (I'm still plunking away at the fluid model for Darwinbots3 but I'm at least several months away from something releasable on that front.  There's not active Darwinbots2 development going on right now, as far as I know).
