calculating without gradient (might want to try a different optad=VALUE)

[stubbsrl]

I have run TreePl by first running Prime and copying and pasting the generated values at the bottom of the configuration file:

opt = 4
moredetail
optad = 1
moredetailad
optcvad = 1

I then run the cv part of the program and change the smoothing parameter. Once I run the tree my results seem generally fine but "calculating without gradient (might want to try a different optad=VALUE)" is output a few times. Same with "calculating without gradient (might want to try a different opt=VALUE). These values (opt and optad) were generated from the Prime output, so how do I decide what other numbers to try?

Thanks

I have seen the same warning in my analysis too!
