My thoughts exactly. Though I was leaning more towards experimenting with
different Evolutionary Stable Strategies (ESS). See if an RCX using
tit-for-tat ESS can invade a population of RCXs using a different, more
greedy, ESS. See Robert Axelrod's book for more details: "The Evolution of
Cooperation".
"Invade" can be defined however you wish: gather more blocks, reach a goal
first, travel the most distance etc.
My interests tend to lean towards emergent cooperation: can 6 RCXs do
something together as a team that one RCX cannot do?
Another interesting task: program "flocking" behaviour. The rules that govern
schools of fish or flocks of birds are deceptively simple. Sort of "Stay a
constant distance from your nearest neighbour" and "Always head towards the
perceived point of greatest density of neighbours". These two rules allow a
flock/school to stay together, avoid obstacles and still regroup into a flock
as they fly/swim around things.
So what is the collective noun for a group of RCXs? A "brick" of RCXs :-)
The fun part is that you can tie this in with a lecture on
Evolutionary Computing and Emergent Cooperation.
Regards,
Mark
