This leads to the problem of data fitting within an appropriate model. Newton's method is used as an upgrade of the previously developed most promising discrete optimization heuristics showing an improvement in both performance and the quality of solutions. This experiment also indicates that a combination of an algorithm that finds promising initial solutions as a preprocessor and Newton's method may be a winning idea, at least on some datasets of instances"},{"@xml:lang":"sl","#text":"Zagotavljanje učinkovitih delovnih procesov je ključ do uspešnega in konkurenčnega podjetja. Še posebej velja to za proces razvoja svetil. Tako se v želji po hitrejšem in cenejšem razvoju velikokrat poslužujemo računalniških simulacij prostorske porazdelitve svetilnosti svetila (fotometrija), namesto realnih meritev. Simulacije namreč omogočajo testiranje svetila z različnimi optičnimi elementi v relativno kratkem času, kar omogoča preizkus več variant izdelka. Vendar pa so rezultati simulacij v celoti odvisni od vhodnih podatkov. Tako se lahko kar hitro zgodi, da se simulacijski rezultati ne skladajo z dejanskimi meritvami"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-OOCZBB6W","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-OOCZBB6W"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-OOCZBB6W/552d6cc0-e64a-42d7-811d-2349aba9d7cb/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-OOCZBB6W/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-OOCZBB6W"}}}}
