yorick-optimpack 1.3.1+dfsg1-1 (amd64 binary) in ubuntu maverick

 OptimPack is a portable C library which implements algorithms for
 optimization of large scale problems with bound constraints. Large
 scale means some million variables (e.g. pixel values) or more.
 .
 The most important algorithm is VMLM-B: a variable metric method with
 limited memory requirements and, possibly, bound constraints on the
 parameters. The algorithm is based on limited memory BFGS updates
 with Moré & Thuente inexact line search and gradient projection to
 account for bounds.
 .
 This package contains a Yorick plug-in based on OptimPack.
