Multi-parametric disaggregation technique for global optimization of polynomial programming problems

Teles, João; Castro, Pedro; Matos, Henrique - In: Journal of Global Optimization 55 (2013) 2, pp. 227-251

This paper discusses a power-based transformation technique that is especially useful when solving polynomial optimization problems, frequently occurring in science and engineering. The polynomial nonlinear problem is primarily transformed into a suitable reformulated problem containing new sets...
