Hi Craig, ... It looks like the cause of your problem is that you are modifying the value of a ephemeral random "in place" in the GP tree, without cloning it

Hi Craig, ... It all depends on how you did your code and how the logic of your system is done. But in general, it looks to me like a method prone to have

I'm sorry that this issue has come back. Sorry also to add to Prof Gagné's queue. I had convinced myself that my jiggle mutation was working in conjunction

Hello, I noticed I have duplicate individuals in my population. For example the first individual of the generation 0 is copied two times in the generation 1. I

I've been working away adding the "glue" code between Open BEAGLE STGP and my pre-existing texture synthesis library. The other day I started seeing

Hi, ... As I said, it depends on the circumstances. When this is done, a warning message is given in the logs. ... That simply because the GP crossover

Christian Gagné — Fri, 06 Nov 2009 18:20:21 GMT

Hi Linge, Open BEAGLE normalize probabilities only when that is required. In the case your are presenting, where all operators are done one after the other, no

Re: Does open beagle normalize probability?

Craig Reynolds — Fri, 06 Nov 2009 18:14:58 GMT

... I'm not the authority, but I think the answer is yes based on a recent reply from Christian: ... I was also curious if there is a significance to the

Does open beagle normalize probability?

Bai Linge — Fri, 06 Nov 2009 16:30:27 GMT

Dear all, I have a question with open beagle's normalization of crossover, mutation and reproduction probabilities. For example, If I specify crossover and

To be clear, my goal was to get my application working as quickly as possible. Your concern is the design integrity of Open BEAGLE. (Well and supporting your

Hi Craig, Ok, so you added a mutate() method to the T type, that is the Doubles, Fraction, etc. It seems to work well for your case, so that's fine for your

Craig Reynolds — Wed, 04 Nov 2009 02:35:26 GMT

Finally this works! I seem to be successfully doing "constant jiggling" on my three classes of "ranged Doubles". I tried two version of where this new mutate

Thanks Christian, with your comments I found my problem. I needed to add 3 items for the ".primit" names to my configuration file:

Hi Craig, ... It is difficult to tell being where I am. That's true that the MutationEphemeralOpT looks for primitives of a certain name, by default "E". That

In my STGP application I now have 3 kinds of "ranged numeric values" (Fraction, SmallFloat and SmallPosFloat (actually double not float)). For each I define
