Remark on the Updated Truncated Newton Minimization Package, Algorithm 702
A truncated Newton minimization package, TNPACK, was described in ACM Transactions
on Mathematical Software (Vol. 18, pp. 46-111) in 1992. Modifications to
enhance performance, especially for large-scale minimization of molecular
potential functions are described here. They involve three program segments
of TNPACK: negative curvature test, modified Cholesky factorization, and
line-search stopping rule.
