[all] ApacheCon North America 2014
The Call For Proposals for ApacheCon NA, 2014 will go out in the next couple of weeks. PMCs have been asked for volunteers for the Content Committee to review proposals related to their projects. Before we all rush to raise our hands, we thought it best to get a sense for what talks might be proposed the community. Is anyone planning to submit a proposal? The theme this year is really wide-open, i.e., there is no pre-established theme for the whole conference of pre-determined track structure.

[math] BOBYQAOptimizer hang
I ran into a case that BOBYQAOptimizer hang in line 485. trsbox is pretty complex method and I'm not familiar with the algorithm. It seems going into infinite loop between different states. final double[] dsqCrvmin = trsbox(delta, gnew, xbdi, s, hs, hred); Here is the test case for it. After reducing the value to 2.24 it hang in trsbox method without progress. Can someone shed light on what might be happening, and how to deal with it? Thanks.

The short story is that BOBYQAOptimzer is not really supported. The long story is on the bug-tracking system: https://issues.apache.org/jira/browse/MATH-621 Sorry, Gilles - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
