An efficient one-dimensional GO method using local tuning on the behavior of the objective function is generalized to the multi-dimensional case by the diagonal approach using two partition strategies. Global convergence conditions are established for the obtained diagonal geometric methods. Results of a wide numerical comparison show a strong acceleration reached by the new methods working with estimates of the local Lipschitz constants over different subregions of the search domain in comparison with the traditional approach.", "revisions": [ { "version": "v1", "updated": "2011-03-18T17:02:26.000Z" } ], "analyses": { "subjects": [ "65K05", "90C30" ], "keywords": [ "partition strategies", "local tuning", "multi-dimensional multiextremal objective function", "global convergence conditions", "diagonal geometric methods" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.3665K" } } }
