Is it possible to save the best model at the middle of iterations?

[sathiyabalu89]

Generally wapiti model stop the iterations when the error is same for 5 iterations. I have fixed maximum iterations to 500. After few iterations, the err value just fluctuate little and because of this the max iterations is done. So is it possible to save the best model at the middle of iteration so that the overfitted model can be avoided? Also, can you please explain on the two errors values shown in the output?

Train the model with l-bfgs
