Re: [Tutor] Encoding and Decoding

Hi Kent, I have yet to get into OO, and the GA that I'm using was done in this way, so I can't mess with it that much. So for now yes, the list has to be a flat element containing all this info. I have been reading about OO lately and a element class seems to be a good idea, I'm working on it

[Tutor] Encoding and Decoding

s a little messy but this is because List [0] = Tens X position List [1] = Units X position List [2] = Decimals X position List [3] = If < than 5 the number is negative, else is positive Then if the result is List = [6, 1, 2, 3] the X position equals -612.3. This is the same for the Y position. If there are 10 elements the list is going to be 80 integers long and if there are 100 elements, well you get a very long list... With this in mind my question would be, how can I keep track of this information? I mean how can I assign this List positions to each element? This is needed because this is going to be a long list and the GA needs to evaluate the position of each element with respect to the position of the other elements. So it needs to know that certain numbers are related to certain element and it needs to have access to the size, level, name and parent information... I hope that this is clear enough.

I mean, no matter how many 'Levels' it will allways get them right (levels so far are only integers).
