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

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

... 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?

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

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

Hi, I just wish to post a patch I've used to fix all build errors I came across when compiling Beagle 3.0.3. Mostly fixes patch holds is a matter of some

... Sigh. The line were EphemeralFraction is inserted into the primitives had been commented out for testing. Thanks for pointing me to the problem, sorry

Hi, ... Ah. There is maybe something you trying to do that require this operator= for assignment of base object to derived object to be called. ... That's

... To be clear, "I" do no such assignments, at least not explicitly. All I do is write the two definitions below and then add EphemeralFraction to the

Hi Craig, ... Ah, I didn't notice this from you explanations/code. Indeed, assigning base object to a derived object is not handled by default by the C++
