Abstract: | This paper introduces an algorithm for minimizing a single-variable locally Lipschitz function subject to a like function
being nonpositive. The method combines polyhedral and quadratic approximation, a new type of penalty technique and a safeguard
in such a way as to give convergence to a stationary point. The convergence is shown to be superlinear under somewhat stronger
assumptions that allow both nonsmooth and nonconvex cases. The algorithm can be an effective subroutine for solving line search
subproblems called for by multivariable optimization algorithms.
