Random loading of initial population into islands

Hello,



When the "Use strategies from initial population" is enabled and the islands for the genetic algorithm are populated, are they done so sequentially, or is it randomized?


If it is not randomized, can it be made to be randomized, or at least can the option be given to randomize the loading of the strategies?


The motivation behind this request is so that the islands look different each time the GA restarts.


Thank you!

One of the things this would let us do is create a large set of strategies via the Random Build process (i.e. several thousand), and then pull a random subset (i.e. 400) into the Initial Population randomly with each cycle of the Genetic Algorithm. I believe this will result in more diverse results from the GA process than we can achieve now. 


Note: It's important that the GA randomly sees the Initial Population each time it restarts (i.e from stagnation or from the max number of generations being reached). Otherwise the desire effect will not be achieved.


Thank you!

it is randomized, but they are not randomly selected on every restart. We'll implement it.

Hopefully we don't have to retest them every restart....

Status changed from New to Fixed

fixed, initial population is chosen randomly with every evolution if there are more strategies than required in initial popoulation databank.


bendx77 - it is retested only once

That's great, thanks Mark! I think this will really help create more diverse strategies within genetic evolution.
