Hi, I wish I could get a primitive from another primitive. Better explaining, I did a primitive called Bcond (abbreviation of Boundary Condition) and I have...
Hi Christian, Now I changed a little bit my code, but I'm getting some error. Is that where I made the mistake? void Bcond::execute(GP::Datum& outResult,...

Hi, I am interested to implement call some ADFs in my GP. Trying to understand de 6-even-parity problem, I have found some doubts. As I understood, the ADFs in...
Hi Dan, ... No. There is 6 inputs to the parity problems, the 6 input bits. But we use 2 ADFs, each with 2 arguments. ... The ADF primitive is a call to the...
Hi, I am considering using Beagle to implement context-free grammar constrained GP (making use of strongly typed mechanism) . Could anyone tell me wether...
Hi Yin, For your specific case, I don't think you will need to heavily customize Open BEAGLE. A generic constraints handling mechanism already exists in Open...
Hi fellowship of Open BEAGLE, To coincide with GECCO 2003 (Genetic and Evolutionary Computation COnference), I am pleased to annonce that the Distributed...
Yes. I don't like the blind validation methods to ensure feasible solutions. It's better to implement some direct methods. for strongly type, I used my own...

Hi. I've written some postscript and C++ code that takes an Open Beagle tree and converts it to a pretty postscript EPS file. For example, (+(E[0.54],x)) ...
I have just encounterd a problem with an individual with a fairly long tree (some 700 characters). The individual was not parsing correctly and I've pinned the...
Hi, I imagine that the best individual of each generation could be captured by some stack (I don't think is HOF, am I right?). What is the name of that stack?...
This is really cool! I'm glad to see Open BEAGLE users developing such tools! I plan to develop visualization tools for Open BEAGLE in the middle range. I'll...
