Currently, I'm getting used to ECJ and it is really cool. I focus on
symbolic regression and thus I've had a detailed look at tutorial 4, which
tries to find a function that maps two input values to one output value.
However, for my current task, I have two input values and two output values
for which I would like to find a function via symbolic regression. How do I
I tried using two trees per individual which works sometimes well. Most
often one of the trees seems to be stuck and doesn't evolve so that the best
individuals of nearly all generations share a same tree. Do you have any
idea why this happens? Since I'm using the default values (1024 individuals
per generation, tournament size of 7), this seems unlikely to me.
Thanks in advance!
