Bot Tavern / multibot theories
« on: September 18, 2005, 04:45:09 PM »
ok write here about all concepts how multibots might work, which strategies they may use.

I will start with my thoughts.

1There seems to be an agreement , that the movement of multibots is extremely hard to coordinate (that is if there is not a "leader" and the other just  adapts there speed and ditance like swarms usually do)
so the easiest way to avoid this is to create a stationary multibot.
Whats the role of a stationary bot?
There are 2 food gaining mechanism for him,
 either relying on food that moves into his reaches(he could exploit attraction mechanism, like use a virus to hypnotize prey to come to him)
or managing an source of algae/veggies, which means limiting his energy and protecting his foodsource from extern influences.
To optimize the ratio protection(energy use) and energy gain.The outer surface has to be mimized while the inner surface has o be maximized(you can not feed of algae surrounded by other algae)(large free  areas abundant of food would be some quite good saftey puffers against non algae transporting  bots)

2A multibot invests quite much energy to reach full growth, such creating full
 developed progeny would probably slow down his reproduction to much.
The most practibable solution I think is the production of spores which will always result
in the fact that a multibot will have to go trough different lifephases

3Because a multibot invests so much to complete his structure and his numbers are lower compared to single bots  he can not afford to die that easily.
Result is that to be praticable an multibot has to have an really strong and flawless
as possible immune system.

4So far I can imagine three growth patterns :
First after surrounding an single algae, a layer growth with cells alway trying to point outward(where no other bots are), the inner structure then could be formed by letting inner cells die.For example when a cell binds to an algae and has 2 non algae neigbors these could be forbbiden to bind algaes such algae and non algae binding cells  would alternate after enough outer layer would have build up the nonbinding cells would die, the binding cells would ensure they are connected to a neigbour of their own species(the outer layer)this new connection partner then would be converted to an algae binding cell, their neigbors to nonbinding.After several cylces of this the inner surface would have grown.
Second concept is the alternation of layer growth and ring extension, inspired by certain tree growth mechanisms. The basic thought is when the outer layer extends
drastical the inner layer connections will be dragged apart the inner cell would register that stress and cut ties if the stress reachs a certain lvl.This would also result in a greater inner surface.
Third an extending ring that grows string from his inner surface, here also could be used an alternation system trigerred by algae.

Well thats what I could think of till now.

DNA - General / my tryouts. Help plz

ok I tried to design a search gene but for some reason it does not work were is the mistake?

*.eye4 *.eye5 > or
*.eye3 *.eye5 > or
*.eye2 *.eye5 > or
*.eye1 *.eye5 > or
*.eye6 *.eye5 > or
*.eye7 *.eye5 > or
*.eye8 *.eye5 > or
*.eye9 *.eye5 >
*.eye1 3 mult *.eye2 4 mult add *.eye3 5 mult add *.eye4 6 mult add 10 div
*.eye9 -3 mult *.eye8 -4 mult add *.eye7 -5 mult add *.eye6 -6 mult add 10 div
add .aimsx store


so what it should do, if any target is nearer then  the target in front it should
rotate based on the attractivity of the side. I weighted  the values to calculate attractivity.

Well in any case the rotation is to weak , but the real problem is it only rotates correctly clockwise never anticlockwise.

Ok just a thought but would it be possible for a robot to copy all his Dna into an algae trough virus insertion and then deleting the algae Dna ?
If so such robots would easily become indepandent from feeding,the coudl even become independant of reproducing by just mimicking the enemys(eye number)
and then inserting their own Dna into it.

Probably that idea was brought up before but as I said my forum search never works.

Well I am new found my way trough some links about artificial life and hell of confused  :huh: .
(I already experienced the same thing when finding an a-life game called E-den.)

There is so much to learn and its so difficult  to find the right informations.
For example the meaning of > in the syntax and which numbers already have functions and which not.

Ah but I will not lose hope and try to learn the stuff  :D

some resume on my design thoughts:
First I thought about the design of a circle surrounding the algae, however I found that this design was already discussed.

My second thought is to orient the devolpment of multiple cell organisms according to the immune system.
Protection against outer influences is always a main drive for forming collective structures and a large amout of our bodies resources are used for this purpose,
Not to mention that the immune system is one of the highest  developed sytems in nature(if I remember right the immune and nervous system are somewhat related
in their origin)
As the main outer influences in this simulation  are other organism this strategy seems most appropriate for me.
*detailed information after point three

My third idea is  implementing a network of multiply cells with everchanging connecting and the ability to ordered cell death.This concept basically stems from the fact that cell death plays a big role in the forming of our body structures.
With the right basic instructions this could lead to complex structures.
(for example creating inside the body  where algae could grow)
In the best case this could even to the forming of simple information processing networks.

*immune system thoughts: repair and backup system can be provided by multiple cells, if cells regulary compare certain values that would normally not be changed
and overwrite the value with the most common in his neighbors virus infection can be healed.
One of the most important abilities of the immune system is to identify foreign objetcs and learn according reactions (specific antibodys etc) as you can only fight if you see your enemy,thus certain cells could be used as information storage(memory) and specialize in the idenfication of dangers , such the cell could also learn the success of certain behaviour associated with certain objects.
(the concepts of association is one of the moszt powerful mechansim of information progressing).
A skin is a defensive mechism of the immune system and consist of highly defensive outer cells the question stays however what use inner cells could have?
The most promising scenario for inner cells would be integrated algae or an inner digestion system which however would require a "mouth".
Another scenario is that of inner reproduction which leads to a "hatching".
An immune system could rely on the creation of a certain "pass" or best multiple passes as long the pass does not mutate  identification is possible and a biodiversity of passes combined with other tests would guarentee populations that are immune to certain diseases/infiltrators.
