Dear Group I tried to make a small application in Open Beagle which compares values in an array containing floating point numbers. Using the primitive set from...
Hi Helmut, ... The problem here seems to be caused by the fact that you don't use the strongly typed initialization / crossover / mutation operators. Spambase ...
I am trying to perform a multi-objective minimization using the NPGA2 operator. Looking through the source in NPGA2Op.cpp, I noticed that the Fitness objects...
Hi Jim, ... Yes. FitnessMultiObjMin inherits from FitnessMultiObj and overloads the method isDominated for minimization (isDominated is virtual). NPGA2Op will...
Hi Mauricio, ... Well, here you will need to work directly on the structure of the individuals for your fitness evaluation, by-passing the calls to the tree...
Hi, I'm trying to get the best-of-run individual after each generation. In order to achieve it, I wrote the following code: Beagle::Individual::Handle...
Hi Dan, ... First, be sure that you set parameter 'ec.hof.demesize' to a value >=1, in order to have an deme's hall-of-fame with a least one individual. It ...
It worked fine. I put the demesize = 1 in order to take the HallOfFame[0] as the best of run Member. Thanks a lot, Dan. ... Outgoing mail is certified Virus...
... Hash: SHA1 Hi, I'm trying to approximate the answer to a function for which I can numerically integrate, but, I want something that will compute faster......
Hi Binesh, ... Just one note here, I am skeptic that using GP will perform faster that any deterministic approach. If it is only a question of quick ...
... Hash: SHA1 ... Hi Christian, I suppose what I mean by quicker, is the way numerically integrating Integrate[slope X + intercept, {X, from, to}] breaking it...
Hello Binesh, ... Definitely not. GP is a brute force blind search paradigm that needs huge computation time compared to most classical deterministic numeric ...
Hi everyone, The following is about symbolic regression. I've used this example http://beagle.gel.ulaval.ca/refmanual/a00871.html#a0. I know that my equation...
Hi J-P, Your question appears pretty much related to the homework 3 of the course "Algorithms for the Engineer II". I advice you to ask your question to a...
Hello Open BEAGLE users! There is actually a contest organized by IBM to port open source applications on LinuxPPC64 architectures. http://www.linuxonpower.com...
Unfortunately, IBM are being restrictive: From the FAQ: "Why are only US contestants elligible? Regretfully, because of time constraints for obtaining legal...
I downloaded beagle-2.1.5 to be compiled on redhat 9.0 with gcc-3.4.2. I can't find anything about this particular problem on the archive. Any idea ? Thanks ...
Hi Tran, ... I don't have access to a computer where gcc 3.4 is installed. This seems to be quite a simple compiler error. My intuition would be to specify the...
Hello, I had the same problem when recompiling version 2.1.5 after upgrading the version of the compiler to 3.4 (on a Mandrake 10.1 Community). I solved it by...
Hi, Thanks Laurent for the tip. I applied the changes suggested below, hoping that it will solve the issue with gcc 3.4. It will be in next release, 2.2.0,...
Hi everyone, I proudly announce the release of Open BEAGLE version 2.2.0. You can get your copy at: http://beagle.gel.ulaval.ca http://beagle.sourceforge.net ...
Hello everyone, The Open BEAGLE developers are proud to announce the release of Distributed BEAGLE 0.9.2. This is a minor release of one bug fixe and one...
Dear all, I'm going to use your library to implement a GA for a project. By checking the source autoconf and automake config files and m4 macros, I noticed...
Hi Joao Luis, ... These are interesting suggestions, especially the fact that acinclude.m4 macros can be put into separate .m4 files. I take note that the ...
Dear Sirs, I started to look at Open Beagle and I really like the architecture of it - in comparison to GALib that I used before it looks way more structured...

Hi Yuryi, ... Well, you problem seems more with the typing of the primitives you are using. Be sure that there is terminals of the four data types you are ...
