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....
Hey ! :) I am indeed using a single Tournament selection Op. What should I use instead? Here is how my .conf file is currently looking like: (I am currently...
Hi, Replace the SelectTournamentOp by SelectRandomOp in your configuration file, as it is done in the configuration file of knapsack. NSGA2Op is always doing a...
Thanks! It really helped. But I have another problem. In the end, when I look at the .csv generated, which should show me the pareto front, almost all the...
Hi, ... All depends on the nature of your problem. If your objectives are not negatively independant, such that improvement in one objective doesn't degrade...
Hello everybody, I am trying to use Distributed Beagle but I have some troubles with it. If you use a script to start the server, the evolver and then...
Hi Noémie, ... Ctrl-c is one of the good way to stop the server. The server is coded to support elegant termination through Ctrl-c. Another approach is to do...
Thank you Christian, I am not sure about something : Where should be placed configuration files of clients? They can be at the same place (for example in the...
Hi Noémie, What is important point is that when you launch a binary on a given computer it should have access to the configuration file, either at default...
Hello, I used Open Beagle 3.0.3 to create my project but I installed Open Beagle 2.2.0 on another computer in order to use Distributed Beagle 0.9.2 But I get...
Hi Noémie, In order to allow us to understand your problem and give you support, you need to be more precise on the errors you are getting and the way you are...
Hello, the errors that I had were about some methods which were not defined correctly : "undefined reference to" .. I seems these methods of the version 2.2.0...
Hi Noémie, ... On that point, you really need to check with peoples in your lab that are good on unix, for example sys admins that offer some user support. ...
Hi, the command "xml" doesn't work (I still don't know why) but I realized that I can put the executable's path. So it is working. :) Thank you, Noémie...
Hello I am a newcomer and I encountered an error which I couldn't correct. I set-up a .conf file; ga.init.minvalue and ga.init.maxvalue for initialisation and...
Hi I get these errors all the time, its just something wrong in your config (usually). For example, your vectorsize is 16 yet you've initialised 15 values /...
Hi Shanon Thanks for your post. I looked at code segment for GAIntVector initialisation, and it seems last element of init.minvalue/maxvalue is used if...
You could try that, I dont know if it would work. I would create a copy of GA-InitIntVecOp and modify it, and add this operator in main program for the...
Hi Instead of making any modifications to library's code, I used positive values for all parameter ranges within .conf file, e.g. [-2,2] scaled to [0, 4], and...
Hi, As you spotted it, the problem is a know bug that has been fixed last year in the CVS/SVN version of code, but is not part of version 3.0.3 (which is older...
Hello, My intention is a little bit different than what was described here: http://tech.groups.yahoo.com/group/openbeagle/message/1305 After completion of...
Hi, ... Yes, that's totally possible. You could fetch the information about the Pareto front through the C++ API, in order to do what you described. The only...
Hello, I tested Spambase of Dbeagle but I only got the first population. What can be the problem? Do you think it is related to the evolver? Here is the result...
Hi Noemie, By experience, it is common to get spambase example to stall. The problem is that this is an example of strongly-typed GP (STGP), and that with a...
Thank you for your quick answer. The thing is I use STGP in my project (and I can't make it work) that's why I've tested Spambase example . I looked at...
Hi, The thing here is to increase the minimum depth of some parameters, as the spambase example typing require that the trees are at least of 3 levels (or...
