TMVA kCuts output wrong

TMVA

Hello everyone,

When I’m using kCuts to optimize nine variables cuts, there are some wrong output that one variable should be less than a certain value, and I set the upper limit to a small value (such as 0.0606) and down limit to -999, but TMVA output 10^30 for the variable. Which experts could tell me what the reason is? Thanks in advance.

Best regards,
Qiuping

Hello moneta,

I used the TMVA package (kCuts: GA). For a certain variable (e.g Var),
its CutsRangeMin:CutsRangeMax are respectively set to -999:0.0606, but the output gave me CutMin=-0.00407642 and CutMax=10^{30}. My question is why the max value is more than the CutsRangeMax I set? Thank you very much.

Best regards,
Qiuping

Please send me the files you use and I can understand this. These values are probably set because no sensible values for the cuts are found
