| 2 | Extended Global Convergence Framework for Unconstrained Optimization显示文摘An extension of the global convergence framework for unconstrained derivative-free optimization methods is presented. The extension makes it possible for the framework to include optimization methods with varying cardinality of the ordered direction set. Grid-based search methods are shown to be a special case of the more general extended global convergence framework. Furthermore,the required properties of the sequence of ordered direction sets listed in the definition of grid-based methods are relaxed and simplified by removing the requirement of structural equivalence. | rpád BRMEN Franc BRATKOVI Janez PUHAN Iztok FAJFAR Tadej TUMA | 2004 | Acta Mathematica Sinica,English Series2004，20，3： | 0 |
