Yes I am...
I suppose we should not totally give up our approaches since I have already figured out the fourmule for type of SCRA, it's best to keep the design of every project such that either ANNEvolve or NEAT can be plugged in when ever required.
Problem with me is that I don't ususlly find as much free time as when I joined ANNEvolve, as such I most of the times slower than required.
Mitchel I have few doubts regarding 4Play changing to SCRA type:
1 > Tell which are the files I need to change most.
My guess is Neuron.h/c and Evolve.h/c
2 > The choromosome structure of SCRA which I would like to use and which I have arrived after a lot of thought is different fron what we had.
it will be 2-d array Jagged array kind of thing, I mean having 2 Rows, the first row carrying carrying the respective weights and each of this will have an associated set which will sotre fan out sets.
I am still not very much comfortable of having an fan-out sets but there seems to be no other idea to save calculation.
3 > Tell me when and where you actually introduce new Networks into the evolution, since during that period of time we have to calculate some equations to know whether the network will be FCBA or Pruned or Perfect.
Formulas are something like this :
mN / (s + 1) where N is total number of node
s is skip
m is integer, 1,2,3....
find the minimum m for which the above fraction gets prefectly divisible.
e.g, for N = 27 and S = 11 we have m * 27 / (11 + 1) = m27 / 12 = m 9 / 4
=> m = 4
Now let FO = (float) N / (s +1 ) = 27 / 12 = 2.25
Now is FO * M < N - 1 then this is not FCBA
or else this is FCBA
thus 2.25 * m = 2.25 * 4 = 9 << 27 => Not FCBA
Next it remain to determine whether this is a pruned network
the formule is
1 + (s + 1)n = (x - 1)A + x
where A is advanced...
and n and x are integers and independent variable.
if for and pair of (n,x) the above equality holds than the above network is pruned
or else it is perfect and desiarable.
I have verified the above conjecture with networks of size 30 and is confident that above law holds although I have no methatical prove for it.
4 > Now the question of crossover, If the chromosome if as mentioned in point 2 than it is all about exchanging splice.
Since if we cross two networks having follwoing parameters
(27,11,1) and (32,9,3)
that the essential length of both can something like
x+ a and y + b
after crossover
x+b and y + a such that the length remains the same, we'll not exchange the fab-out sets for the above but only th weights.
Further correction of this idea is needed.
5 > when and where mutation occurs and also what are the thinga to mutate on, I mean N or S or A... I feel only N can be mutated.
I need some help redarding these from you.
work out the above formulas if possible, I will let you know further developmenets from my part.
I would also like to know if i would like to write the 4Play in a such a manner so that with a change of parameter it can become 8 play or 12 play what needs to be done...
