Hi Christian, Previously I worked on an extension to the Beagle::GP::Individual class that stored genealogical information. I'm thinking about updating that ...
Hi Matthew, There is no such scripts actually available. Up to now, the way I proceed to test the read method is to read back several milestones from different...
Hi Binesh, ... You are making good observations here. A principle in the evaluation operator is that we don't re-evaluate individuals that haven't been ...
Hello, everyone, I am new in using Open Beagle. I have a question about how to record the best individual after running GA. When I run one of the GA examples,...
Hello everyone, The Open BEAGLE developers are proud to announce the release of Distributed BEAGLE 0.91. This release is mostly bug fixes and some suggestions...
... Take a look to the milestone file written a the end of the run, by default file 'beagle.obm.gz' (gzipped XML on Linux) or 'beagle.obm' (plain XML on...
... I would also recommend, if you often want to extract the best indiviudal, that you consider the software xmlstarlet (http://xmlstar.sourceforge.net/)....
... I implemented the functionality to have a min/max range per parameter and the capability to define intervals of valid values for each parameter resulting...
Hi Binesh, There was some problems with your configuration files, expecially in the definition of generational breeder. I did some corrections (attached), it...
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...
