Zl. Sheng et Ma. Wolfe, AN INTERVAL ALGORITHM FOR NONDIFFERENTIABLE GLOBAL OPTIMIZATION, Applied mathematics and computation, 63(2-3), 1994, pp. 101-122
An interval algorithm for constrained nondifferentiable global optimiz
ation in which an exact penalty function is used is described, and the
determination of the penalty function parameter is discussed. Numeric
al results are presented.
