Hello! I seem to be unable to make a batch GP job (several consecutive jobs) with DBEAGLE, so I was wondering if You could help me in this matter. I tried with...
Hello, The db.restart options means that the evolver will create a new deme (if equal to 0) or use the only already in the server's database (if equal to 1)....

Hello! I have been trying to run a steady-state distributed GP, but I was unsuccessful. I tried replacing the contents of a MainLoopSet with a SteadyStateOp...
Hello, Steady-state does not make any sense in a distributed environment (master-slave) because fitness evaluation would be made one individual at a time... ...
... environment ... individual ... I'm sorry, we have been working on a parallel GA several years ago and I just forgot that it needs additional parameters to...
... Distributed BEAGLE can work with multiple evolvers, but only on a deme level (evolution of demes, not the whole population)... so I guess you could make...
Hi Thomas, ... The correct answer is (2), only modified individuals are re-evaluated. ... You should invalidate a fitness in order to force re-evaluation. To...
Hello! I'm experimenting with multiple evolvers in DBEAGLE, so I would like to check if I understood the mechanisms correctly: - if I start 1 server and 2...
Hi, ... No, DBEAGLE is connection less. Clients (fitness evaluation or evolution) connect to the server and ask for individuals that are ready to be evaluated...

... Ok, here's the problem that I can see: you are using 4 demes of 500 individuals each. Option of the second evolver should be set to db.restart = 1 if you...
Well, it seams that I broke the support for multiple evolvers running at the same time. Multiple demes still works, as restarting an evolver. I should be able...
Hi, Has anyone successfully compiled openbeagle using intel's c++ compiler? I am attempting to do so by running: /configure --enable-optimization CC=icc...
Hello, I tried quickly to compile a fresh copy of Beagle 2.2.0 with Intel C++ Compiler 8.0 (the version I have on my computer) using the same options you gave....
I am trying to read in a milestone, but Open BEAGLE 2.2.0 crashes right after reading in the milestone file with the following error: ... "Assertion failed." ...
Hi Jim, ... For me, this is probably a misuse in the configuration file, or something similar. When applying the CMA-ES (mu,lambda)_w replacement strategy, the...

I'm working on a technique that requires some form of niching (e.g. fitness sharing). I'm just wondering if it has been done in Open Beagle? Thanks MH...
Hi, ... Niching has been implemented in the context of multi-objective selection operators (NSGA-II and NPGA2), but in a very specific fashion. Otherwise,...
I need to implement differential evolution, which in principle, will crossover between 3 individuals rather than 2 as in normal crossover. I read the code in...
... My experience is with the GP side of OpenBeagle. I'm not sure if GP is what you are working on, but I suspect that the difference wouldn't be great if you...
... One more thing. If you get Beagle from the CVS sources then there's a test directory that has something you might find useful. One of the problems with...
Hi, ... I would add that the abstract Beagle::CrossoverOp should in fact be named something like Beagle::TwoParentsCrossoverOp or such. For the moment, all the...
