Calling libLBFGS from within YAP

[Bernd Gutmann-3]

Hi all.

I guess not so many people are using Prolog for numerical optimization  
problems. For the few amongst you trying to minimize a function
f(x1, ... , xn)
in YAP: There is help. :)


I just finished a small interface to libLBFGS which is a fast C  
library to perform this task. All you have to do is, provide a  
predicate which calculates the function value F(X) as well as the  
gradient vector and then you let libLBFGS do the rest for you.

YAP-LBFGS is a module providing the functionality of libLBFGS within  
YAP. It's tested and works nicely under Mac OS and also (if you're  
willing to change the Make file) under Linux.

If you're interested have a look at http://www.cs.kuleuven.be/~bernd/yap-lbfgs/
In case you find bugs or have questions, send me a mail.


(Sorry in case this mail was sent twice - I'm struggling here with the  
security policy of our departmental mail server).

Kind Regards
Bernd

Hi Bernd

Thanks! It looks like a nice package. If there is interest I will be
happy to include it as a package in the YAP distribution.

Cheers

Vitor
