convergency

[waynezw0618]

Hello
I am trying to use geppy to generate a formula for my data set. from the output none of them are small. what should I do to check the convergency of the results?

gen     nevals  avg             std             min             max        
0       100     6.37847e+09     2.28418e+10     3.40389e+09     2.21588e+11
1       99      6.42103e+09     2.1601e+10      3.39555e+09     1.91279e+11
...

199     99      1.71354e+12     1.61272e+13     9.40506e+08     1.6203e+14 
200     99      5.36542e+09     2.55552e+10     9.40506e+08     2.59318e+11

after introducing linear scaling , it looks like:

998     99      0.0477558       0.0260866       0.0153056       0.152724 
999     99      0.0438472       0.0248198       0.0153056       0.151477 
1000    99      0.0486656       0.029362        0.0153056       0.150031 

I can only see min decrease with gen while others does not change.
I am wondering how can I determine whether my result is converged.

How to determine convergence is not coded in geppy. You can set the max number of generations, or alternatively, or stop if you observe no improvement for consecutively k generations, where k is a parameter.
