SymRegression doesn't work, please help - verkert - 10-12-2015 02:11 AM

Attached is my script.
howere, when trying to run the SymRegression here is what I get :
js=SymRegression("test.conf")

Hello,

I do not have problem to run symbolic regression and I use exactly the same Java calls as in in your Jython script, but I'm using the standard example of the input file as that posted to the DMelt database examples. When I ran such script, I get a correct symbolic regression output (attaches).
I think there is a problem with your configuration file.

best, Tania
