I'm doing my first steps in Beagle and have immeadiatly problems. I wrote the symbolic regression example within a MVC Express project, which is configured ...
Hi, You're problem seems to come from the WIN32 version of the PACC_AssertM macro. Take a look to the file PACC/Util/Assert.hpp of beagle, line 55. ... The...
Hi Christian, after some search related to what you said I finally fixed the problem: I don't know if it helped to switch the line to ...CA2CT ... because my ...
Hello, I'm facing a little problem with the hall of fame in a GA optimization. I want to control its size. In mono-objective, there is no problem. In...
Hello Bastien, ... You put the finger on a small but real incoherence with the knapsack example. The point is that the knapsack example use the default ...
Hi, In a previous message #759, it was indicated how to get the best individual in each generation (which could be different from the best individual in the...
Hello, Your message is not totally clear. What do you want precisely? To extract the best-of-generation individual in your fitnesse evaluation operator? If so,...
Hi Christian, You got it. You got what I need. Let me say that what you proposed worked fine! and better than this, you took time to explain (write) how to do...
Hello Christian I'm trying to adjust the weights from a neural net with the GA and compare the archieved results with results from traditional nn training....
Hi Helmut, ... Well, an individual is a container of GA::FloatVector (which is a specialized genotype). So you can't cast your lBestOfHOF handle into a ...
Hello Christian I thank you very much for your efford. The line GA::FloatVector::Handle lFloatVector = castHandleT<GA::FloatVector> (lBestOfHOF[0]); as you...
Hi Christian, I would like to get the N best individuals after each generation (supposse that M is the population size, with M > N)in Genetic programming. In...
Hi, I'm sure Christian will answer your other questions, but I have a suggestion for your "Q2". I have added a SelectBestOp class into Beagle recently. It has...
Hello Helmut, The problem is simply that lBestOfHOF is an Individual::Handle, not an Individual. My error, I wasn't able to "mind-lint" the code correctly. The...
Hello, The solution Matthew is proposing is good and should work. But if you don't want to check out the latest version Beagle from the CVS, I've got another...
Hello! I'm new here... and I'm new to OpenBeagle... Maybe it's a silly question, but I need to know... trying to tune the symbreg exemple, I wanted to add a...
Hi Henry, To me it seems just a mis-configuration of your C++ project. I suggest you two solutions: 1) [Quick and dirty solution] Consider either recompiling...

I am running BEAGLE's GA with float parameters. I would like to be able to specify that for a given pair of parameters, whatever value they take on, they do...
In running the GA, I have a few parameters that get queried way too much at their minimum and maximum values. (My fitness landscape may be like a volcano,...
Hi again Tom, If you need to bias in some way or another the different scales of your values. This is very similar to your other problem, and still pretty ...
... Obviously, for being a Gaussian, the previous equation is missing a minus sign. x'_2 = x_1 + sign(x_2) exp(-x_2 / (2 sigma)) Sorry for that, christian ... ...
Hi Tom, Well, there is no specific solution for this kind of problem in Beagle. This is somewhat quite problem-specific, I don't see a general approach for...
Thanks for the reply, Christian. I understand your approach, but not exactly where and how to implement, and this stems from my lack of understanding of how...
Hi Tom, ... Yes and no. You understand well that you transformation of your data should be done in your EvaluationOp::evaluate() method before evaluating the...
Hi Christian, I'm trying to log at level 7 and get the message: "File log level 7 (debug) is unused as full debug mode is disabled". This is for the beagle...
One reason I am wanting to have full reporting (see previous post) is that I am curious about the Gaussian Float Mutation Operator. Its sigma value is 0.1....
