This is a summary of the author's PhD thesis, supervised by Yaroslav D. Sergeyev and defended on May 5, 2006, at the University of Rome "La Sapienza". The thesis is written in English and is available from the author upon request. In this work, the global optimization problem of a multidimensional "black-box" function satisfying the Lipschitz condition over a hyperinterval with an unknown Lipschitz constant is considered. The objective function is assumed hard to evaluate. A new efficient diagonal scheme for constructing fast algorithms for solving this problem is examined and illustrated by developing several powerful global optimization methods. A deep theoretical study is performed which highlights the benefit of the approach introduced over traditionally used diagonal algorithms. Theoretical conclusions are confirmed by results of extensive numerical experiments.
