%description
Interfacing to Nocedal et al. L-BFGS-B.3.0 (See
<http://users.iems.northwestern.edu/~nocedal/lbfgsb.html>) limited memory
BFGS minimizer with bounds on parameters. This is a fork of 'lbfgsb3'.
This registers a 'R' compatible 'C' interface to L-BFGS-B.3.0 that uses
the same function types and optimization as the optim() function (see
writing 'R' extensions and source for details).  This package also adds
more stopping criteria as well as allowing the adjustment of more
tolerances.
