[math]
Dear list, I'd be grateful for any help on the following: I am using the CMAESOptimizer in the java commons.math3 library to generate a best fit for a model of learning to some experimental data. When I take the best parameters generated by the optimisation and plug them into the model, the fit between the model and the data doesn't match that which I expect on the basis of the optimisation output. In the cases I have checked the optimiser output best fit (the value part of the PointValuePair that comes at the end of the optimisation) is slightly larger than the value I get when I run the model using the parameters from the optimiser output (the point part of the PointValuePair that comes at the end of the optimisation). I have spent quite a long time checking my code and I can't find what the problem is but it occurred to me that there might be something about the optimisation output that I haven't understood properly. Am I correct to assuming that the parameters produced at the end of the optimisation are those that produced the associated best fit value?

Which version of Commons Math are you using? [To figure out what could have happened, it would be easier to have the actual numbers for the parameters and associated cost and the function to be optimized (minimized or maximized?).] Best regards, Gilles - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
Class org.apache.commons.logging.impl.SimpleLog does not implement Log

Installing
Hi, I am trying to install jsvc. I downloaded the bin of commons (commons-daemon-1.0.13-bin.tar.gz) from http://commons.apache.org/proper/commons-daemon//download_daemon.cgi. After extraction I can't find the configure script that is mentioned in this page http://commons.apache.org/proper/commons-daemon//jsvc.html section Building from a release tarball. Am I missing some step? By the way can you tell me if jsvc will allow me at the end to run a java a program as a Daemon whose commands I can simply configure in /etc/init.d under ubuntu?
