A filled function method for nonlinear systems of equalities and inequalities. (English) Zbl 1259.65095
The authors consider the following system of nonlinear equalities and inequalities defined by $$c_i= 0$$, $$i\in E$$ and $$c_j\leq 0$$, $$j\in I$$. The original problem is reformulated into an equivalent constrained global optimization problem of the following form $f(x)= \min_{x\in\mathbb{R}^n}\;{1\over 2}\,\Biggl\{\sum_{i\in E} c_i^2\Biggr\}\quad\text{s.t.}\quad c_j(x)\leq 0,\;j\in I.$ The authors present an algorithm based on the proposed filled function. Numerical experiments are also presented.
