Hi, I am wondering if the individuals of a generation are stored in a file (in the form of a nodes' list for example)? And if not, is there a way to do it? Is...
Hi Noemie, Yes, individuals of a generation can be written to a different milestone file at every generation. For that purpose, change value of parameters...
Hello ! I am new in Open Beagle framework. I am working in the field of time series analysis. I read the manual but it is unclear for me what is the easiest...
Hi Vlad, Can you be more explicit about what you are doing. For instance, which evolutionary computation flavor are you using? Genetic programming? What are...
Hi Noemie, You should modify the parameter in the 'beagle.conf' file. For using other files, you should change the configuration file to use from the ...
Hello, I have a question related to Distributed Beagle. I would like to use different nodes of a cluster to evaluate individuals but I am a little bit...
Hi Noemie, The development version of Open BEAGLE is not documented a lot, although many element of previous documentation still apply. You can take a look at...
Hi Christian, I am very excited about the new framework version, which you plan to release in the summer :] Is there a list of planned changes somewhere? In...
Hi Stig, Changes are quite important, with a reorganisation of the source code in smaller package, and a new build system. Until the next release, I freeze any...
Hi, I'm playing a bit with the cvs version of openbeagle and here is something I came across on my OSX 10.5. When an application is compiled with the flag...
Hi again, I think I understand now what is the problem. Beagle need to be compiled using -D_GLIBCXX_DEBUG -D_GLIBCXX_DEBUG_PEDANTIC in order to work in debug...
Hi everyone I have a problem where each individual / chromosome needs to have these characteristics: 1) Integer valued with min value 1 I think I solved this...
Hi Jean-François, I take note of your observation. We are currently transitionning the build system from the autotools (version in the CVS on sf.net) to cmake...
Hi, ... You need to set the following parameter in the register: - "ga.init.minvalue": Minimum integer value at initialization (GA- InitIntVecOp). -...
Hi All/Christian So Ive built custom evalutionOp according to the examples, but how do I create a custom mutationOp or crossoverOp and initialize them? I've...
Hello, for my project I wanted to generate individuals (only the structure of the trees) thanks to open beagle and then execute the individuals with another...
Well, I am a beginner with open beagle, and I wanted to know how does this operation work. I tried to read its code, but it was just too confusing. I also...
Hi Noemie, ... I would rather advice you to write specific files in your fitness evaluation operator. ... A simple approach would be to define a fitness...
Hi, That's an ad hoc crossover operator I designed for TSP example. That is not a particularly efficient operator, but it is able to cope with vector of...
Hi, my problem was more about the production of the milestone file before the individuals' evaluation. But I found the method serialize() which gives the "xml...
Hello, I would like to know if there is a way to have the index of each individual. I tried to get it with getGenotypeIndex() but the result is always zero :s ...
Hi Noémie, Try Context::getIndividualIndex() instead. It should solve your problem. A population is a Vivarium made of one to many Deme, which is made of one...
Well, I am currently working with a multiobjective problem, and I need to make a graphic that shows how each objective's fitness vary according to the other. ...
Hi, Using FitnessMultiObjMin as fitness type, in conjunction of a correctly configured NSGA2 algorithm (configuration through the .conf file), things should...
Hi, finally not everything is fine. I wanted to write each individual in a XML file (with serialize()) every time the method to evaluate is used and then...
Hi Noémie, Not all individuals of a population are evaluated at each generation. Only those whose genotype has been modified by a variation operator (e.g....
