Pointwise quasi-Newton method for unconstrained optimal control problems. II. (English) Zbl 0795.49023
Summary: The necessary optimality conditions for an unconstrained optimal control problem are used to derive a quasi-Newton method, where the update involves only second-order derivative terms. A pointwise update which was presented in part I of this paper [the first and second author, Numer. Math. 55, No. 2, 159-176 (1989; Zbl 0661.65068)] is changed to allow for more general second-order sufficiency conditions in the control problem. In particular, pointwise versions of the Broyden, PSB, and SR1 update are considered. A convergence rate theorem is given for the Broyden and PSB versions.
