1. A Note on the McCormick Second-Order Constraint Qualification
ABSTRACT The study of optimality conditions and constraint qualification is a key topic in nonlinear optimization. In this work, we present a reformulation of the well-known second-order constraint qualification described by McCormick in 17. This reformulation is based on the use of feasible arcs, but is independent of Lagrange multipliers. Using such a refo

2. Condições de Otimalidade para Problemas Multiobjetivos Irregulares
RESUMO Neste artigo, consideramos problemas de Otimização multiobjetivo com restrições de igualdade dadas na forma F ( x ) = 0, sendo F : U ⊆ R n ⟶ R m e U um aberto não vazio. Consideramos o caso em que a restrição do problema é irregular, ou seja, quando a condição de qualificação de independência linear (LICQ) não é satisfei

3. A DISCRETE DYNAMICAL SYSTEM AND ITS APPLICATIONS
ABSTRACT The main goal of this manuscript is to introduce a discrete dynamical system defined by symmetric matrices and a real parameter. By construction, we rediscovery the Power Iteration Method from the Projected Gradient Method. Convergence of the discrete dynamical system solution is established. Finally, we consider two applications, the first one cons

4. A Full Rank Condition for Continuous-Time Optimization Problems with Equality and Inequality Constraints
RESUMO Condições necessárias do tipo Karush-Kuhn-Tucker de primeira e segunda ordens são estabelecidas para problemas de otimização com tempo contínuo com restrições de igualdade e desigualdade. Uma condição de regularidade tipo posto completo juntamente com um teorema da função implícita uniforme são usados com a finalidade de se alcançar ta

5. A COMPARATIVE STUDY OF STOCHASTIC QUADRATIC PROGRAMMING AND OPTIMAL CONTROL MODEL IN PRODUCTION-INVENTORY SYSTEM WITH STOCHASTIC DEMAND
ABSTRACT This study compares the optimal control model and stochastic quadratic programming (SQP) model of a production-inventory system. A single product, without shortage in the case of a periodic-review policy with stochastic demand and deterioration rate as a function of time, is discussed. The items are subjected to deterioration via storage and the inv

6. OPTIMALITY AND PARAMETRIC DUALITY FOR NONSMOOTH MINIMAX FRACTIONAL PROGRAMMING PROBLEMS INVOLVING L-INVEX-INFINE FUNCTIONS
ABSTRACT The Karush-Kuhn-Tucker type necessary optimality conditions are given for the nonsmooth minimax fractional programming problem with inequality and equality constraints. Subsequently, based on the idea of L-invex-infine functions defined in terms of the limiting/Mordukhovich subdifferential of locally Lipschitz functions, we obtain sufficient optimal

7. LINEAR AND NONLINEAR SEMIDEFINITE PROGRAMMING
This paper provides a short introduction to optimization problems with semidefinite constraints. Basic duality and optimality conditions are presented. For linear semidefinite programming some advances by dealing with degeneracy and the semidefinite facial reduction are discussed. Two relatively recent areas of application are presented. Finally a short over

8. Global optimal path planning of an autonomous vehicle for overtaking a moving obstacle
In this paper, the global optimal path planning of an autonomous vehicle for overtaking a moving obstacle is proposed. In this study, the autonomous vehicle overtakes a moving vehicle by performing a double lane-change maneuver after detecting it in a proper distance ahead. The optimal path of vehicle for performing the lane-change maneuver is generated by a

9. A local-restart coupled strategy for simultaneous sizing and geometry truss optimization
This paper presents an approach for the global optimization of truss sizing and geometry that is based on a probabilistic restart procedure coupled with a local search algorithm. The resulting algorithm is able to guarantee local optimality and provides a set of local optima which contain, with an increasing probability as the number of restarts increases, t

10. As consoantes geminadas do italiano : análise de sua produção por falantes italianos e por aprendizes brasileiros
In this dissertation, we investigate the geminate consonants of Italian using production data collected from Italian speakers and Brazilian learners who take undergraduate courses at the Italian Section of the Federal University of Rio Grande do Sul (UFRGS). The general question that guided our acoustic and phonological analysis is whether Brazilian speakers

11. Sequential optimality conditions / Condições sequenciais de otimalidade
We study optimality conditions generated by the external penalty, internal penalty, internal-external penalty and inexact restoration algorithms, and we show relations with the CPLD, a new constraint qualification strictly weaker than the Mangasarian-Fromovitz condition and the constant rank condition of Janin. We extend the result of the classical Carathéo

12. Sequential quadratic programming and constraint qualification / Programação quadratica sequencial e condições de qualificação
In the context of constrained optimization problems, we face the optimality conditions and also constraint qualification. Our aim is to study with details several constraint qualification, highlighting the constant positive linear dependence condition, and its influence in Sequential Quadratic Programming algorithms convergence. The relevance of this study i
