GSLMinimizer: print level

Quick question about the GSLMinimizer printing. I’d like to get a readout of the progress of the minimizer (the current iteration number and function value). However, when I use SetPrintLevel(3), it dumps all the values of the parameters as well. This slows things down and is hard to keep track of (since I have thousands of parameters). Lower print levels only print things at the end. Any suggestions about how to get a limited amount of data from the minimizer as it’s working? Is there more documentation somewhere on the print level? Thanks!


I have implemented an intermediate level (level = 2), where only the iteration number plus function value is printed. This is now committed in the current ROOT trunk version (revision 39067)

Thank you for your post
