Hi all, I am doing experiment with GP symbreg example. One of the problems I've encountered is that after several generations, the equations became very...
Hi Linge, ... An elitism of 4 individuals in a population of 16 is indeed very strong. Moreover, doing a GP evolution with 16 individuals is quite unusual. ...
... Memory storage could be reduced if you were to also store the "age" of the (individual,fitness) pair. Collisions would mean the age would be reset to...
I have run a number of tests on this and can not determine why I'm getting better results with a single objective implementation as opposed to one using NSGA2....
Is there any way to get generational fitness data for more than one attribute without using the multi objective fitness op? I want individuals to be evaluated...
Hi Adam, ... I see in you multi-objective configuration that you are using tournament selection to generate the offsprings, with tournament size of 5 ...
Hi again Adam, ... Well, I have a slightly different solution that may be a good solution for your problem. You could make use of the multi-objective fitness ...
Is that what is happening what I use this configuration: <MainLoopSet> <SelectTournamentOp repropb="ec.repro.prob"/> <VRPTWEvalOp/> <CrossoverIntVecVecOp...
Hi, Yes, it is was is happening, as long as you are making use of a multiobjective fitness (i.e. FitnessMultiObj) in your code. Christian ... -- Christian...
Hi All, Hi Mr.Christian , I'd like to repeat my great thanks to you for your efforts in developing such an efficient library. I have a small question; I want...
Hi Nermeen, There is lack of portable system calls to get time stamps under the second precision, so I can't give any precise advices. You need to dig the...
You might like to have a look at http://beagle.sourceforge.net/refmanual/beagle/html/d3/d0e/classBeagle_1_1Logger.html#Beagle_1_1LoggerXMLa12 This function can...
Hi all, After downloading the latest cvs Open Beagle, I tried to install it on mac. Both ./bootstrap and ./configure worked well, but after typing make >...
Hi Linge, ... OS X manages libraries differently than Linux. I suppose that this problem is caused by a dependencies that are badly stated in a Makefile, and...
Hi Christian, This is the whole error message: make Making all in PACC Making all in Util make[2]: Nothing to be done for `all'. Making all in XML make[2]:...
I am trying to implement the SPEA2 algorithm into the Open Beagle system. What do I need to do differently for adding a new algorithm, as opposed to a new...
Hi Adam, First, I would invite you to continue the discussion on the developers list, as I think your problem is more related to developments than to the use...
In the most recent cvs version of beagle (and possibly previous versions), several libraries are created by making a single .cpp file which #include's all of...
Hi, I am trying to build a new operator, and linking against a beagle installation to do so. First, I install the libraries and header files into my home...
Sometimes I need to compile an archive in a separate directory for each platform (32/64-bit, Linux/Solaris, etc). However, there appears to be a problem with...
Hi, Warning to other Open BEAGLE users: this are problems with the CVS version of the framework. So ignore that message if you are working with version 3.0.1...
Hi, Well seen. I've just corrected all the Makefile.am files to use top_srcdir instead of top_builddir to specify directories in the INCLUDE directives....
Was thinking about this cacheing business... At first sight I thought it would be VERY useful. You could store the fitnesses in a hash table, then lookup in...
Hi, It is true that we can think of an efficient cache mechanism to avoid evaluating several time the same individual. But given the specificities of GP, I...
... I agree that it would most likely not be useful. The whole idea could (potentially) be put to rest by some empirical analysis of "toy" problems. I'm not...
I am having some problems with the building the latest development version of beagle in visual studio (2005): - I am needing to add include paths to the...
Hi Dan, Most developers are working on Linux, some on OS X, and to my knowledge none of them are using Windows. I usually update the Visual Studio project...
