Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)BOX-QUACAN is a trust-region box-constraint optimization software developed at the Applied Mathematics Department of the University of Campinas. During the last five years, it has been used for solving many practical and academic problems with box constraints and it has been incorporated as sub-algorithm of Augmented Lagrangian methods for minimization with equality constraints and bounds. In this paper it is described its use in connection with Augmented Lagrangian algorithms where inequality constraints are handled without the addition of slack variables. Numerical experiments comparing a modified exponential Lagrangian method and the most classical Augmented Lagrangian are presented.1913156PRONEXFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FINEPConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)FAEP-UNICAMPFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)FAPESP [90-3724-6]
