In this paper, the metric dimension of clockwise-oriented circulant graphs ?$C(n, d)$? is studied. First, an integer linear programming formulation for computing the metric dimension of an arbitrary directed graph is presented, and its computational complexity is analyzed. Using computational experiments, the metric dimensions of graphs ?$C(n, d)$? for ?$n \le 40$? are then determined, and several conjectures and general properties are formulated based on the obtained results. A formula for the distance between arbitrary vertices and an expression for the diameter of the graph ?$C(n, d)$? are derived, and general upper and lower bounds for its metric dimension are established. Furthermore, exact values of the metric dimension are provided for several special families of graphs, including ?$C(n, 1)$?, ?$C(n, 2)$?, ?$C(n, n-1)$?, and ?$C(n, n-2)$?. The results indicate a strong relationship between the parameters ?$n$? and ?$d$? and open several directions for further research on the metric dimension of directed circulant graphs</dc:description><dc:description xml:lang="sl">Metrična dimenzija grafa predstavlja najmanjšo kardinalnost množice vozlišč, s katero se lahko enolično določi vsa ostala vozlišča grafa glede na njihove razdalje do izbranih vozlišč. V članku je obravnavana metrična dimenzija v smeri urinega kazalca usmerjenih cirkulantnih grafov ?$C(n, d)$?. Najprej je predstavljen celoštevilski linearni program za izračun metrične dimenzije poljubnega usmerjenega grafa ter analiza njegove časovne zahtevnosti. Nato so z računalniškimi eksperimenti izračunane metrične dimenzije grafov ?$C(n, d)$? za ?$n \le 40$? in na podlagi dobljenih rezultatov je oblikovanih več domnev in splošnih lastnosti. Dokazana je formula za razdaljo med poljubnima vozliščema in izraz za premer grafa ?$C(n, d)$? ter izpeljane so splošne zgornje in spodnje meje za metrično dimenzijo. Poleg tega so podane natančne vrednosti metrične dimenzije za nekatere posebne družine grafov, med drugim za ?$C(n, 1)$?, ?$C(n, 2)$?, ?$C(n, n-1)$? in ?$C(n, n-2)$?. Rezultati nakazujejo tesno povezavo med parametroma ?$n$? in ?$d$? ter odpirajo več vprašanj za nadaljnje raziskovanje metrične dimenzije usmerjenih cirkulantnih grafov</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-XOZJTY61"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-XOZJTY61" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-XOZJTY61/5c47c202-430e-4824-a839-525851e170fa/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za matematiko in fiziko</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-XOZJTY61/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-XOZJTY61" /></ore:Aggregation></rdf:RDF>
