What method is used in statpt to search transition states

[evgeniy]

Dear TM Community,

I am wondering what method is implemented in STATPT to optimize
transition states. In the TM Tutorial it is said that a qusi-Newton-Josephson
method is used, but no reference is given. Could someone provide the reference?
Many thanks!
