“…The LINCOA algorithm (Powell, 2013b) uses quadratic approximations for the unknown objective function and performs optimization in the presence of known linear constraints. Conejo et al (2013) develop a method which uses local quadratic models of the objective function for problems with a known convex feasible region. General constrained CDFO problems have been studied by Caballero and Grossmann (2008) and Sankaran et al (2010) using local kriging models for the objective and constraints; Powell (1994Powell ( , 2013a developed the COBYLA algorithm which uses local linear approximations for the unknown objective and the unknown constraints which is an approach revisited recently by March and Willcox (2012); Conn and Le Digabel (2013) employ quadratic models for the objective and constraints; Müller et al (2013) use radial-basis function models; and finally Müller and Shoemaker (2014) use an ensemble of various surrogate-models to best fit the objective and constraints of the problem.…”

“…Conejo et al em [1] propõem um algoritmo globalmente convergente de região de confiança para resolver o problema (1) e que gera uma sequência de minimizadores aproximados para os subproblemas restritos. O algoritmo permite grande liberdade nas construções e resoluções dos subproblemas, e o caso de interesseé quando as derivadas da função objetivo não estão disponíveis emboraé suposto que existam.…”

“…In Conejo et al [13], the authors have established the global convergence of a trust-region-based algorithm developed for convex-constrained derivative-free optimization under usual assumptions. Although the problem upon consideration is assumed to be smooth, only the derivatives of the constraints are available.…”
