grafi</a>, un <b>vertice</b> o <b>nodo</b> è l'unità fondamentale di cui i grafi sono costituiti: un <a href="/wiki/Grafo" title="Grafo">grafo</a> consiste in un insieme di vertici e di <a href="/wiki/Arco_(teoria_dei_grafi)" class="mw-redirect" title="Arco (teoria dei grafi)">archi</a> (coppie di vertici, ordinate se <a href="/wiki/Digrafo_(matematica)" title="Digrafo (matematica)">diretto</a>, non ordinate altrimenti). Dal punto di vista della teoria dei grafi, i vertici sono trattati come oggetti senza caratteristiche e indivisibili, sebbene ulteriori strutture relative all'applicazione possano essere aggiunte. Ad esempio, una <a href="/wiki/Rete_semantica" title="Rete semantica">rete semantica</a> è un grafo i cui vertici rappresentano concetti o classi di oggetti. </p><p>Due vertici si dicono <a href="/wiki/Angolo#angoli_di_completamento" title="Angolo">adiacenti</a> se esiste un arco tra essi. Si definisce grado di un vertice il numero di archi aventi origine in esso.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&veaction=edit&section=1" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&action=edit&section=1" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1"><b>^</b></a> <span class="reference-text"><cite class="citation web" style="font-style:normal">(<span style="font-weight:bolder; font-size:80%"><abbr title="inglese">EN</abbr></span>) Victor Adamchik, <a rel="nofollow" class="external text" href="https://www.cs.cmu.edu/~adamchik/21-127/lectures/graphs_1_print.pdf"><span style="font-style:italic;">Graph Theory</span></a> (<span style="font-weight: bolder; font-size:80%"><abbr title="documento in formato PDF">PDF</abbr></span>), su <span style="font-style:italic;">cs.cmu.edu</span>, inverno 2005. <small>URL consultato il 31 gennaio 2020</small> <small>(<a rel="nofollow" class="external text" href="https://web.archive.org/web/20100704212517/https://www.cs.cmu.edu/~adamchik/21-127/lectures/graphs_1_print.pdf">archiviato</a> il 4 luglio 2010)</small>.</cite></span> </li> </ol></div> <div class="mw-heading mw-heading2"><h2 id="Voci_correlate">Voci correlate</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&veaction=edit&section=2" title="Modifica la sezione Voci correlate" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&action=edit&section=2" title="Edit section's source code: Voci correlate"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Grafo" title="Grafo">Grafo</a></li> <li><a href="/wiki/Arco_(teoria_dei_grafi)" class="mw-redirect" title="Arco (teoria dei grafi)">Arco (teoria dei grafi)</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Collegamenti_esterni">Collegamenti esterni</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&veaction=edit&section=3" title="Modifica la sezione Collegamenti esterni" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Vertice_(teoria_dei_grafi)&action=edit&section=3" title="Edit section's source code: Collegamenti esterni"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li class="mw-empty-elt"></li> <li><cite id="CITEREFBritannica.com" class="citation web" style="font-style:normal">(<span style="font-weight:bolder; font-size:80%"><abbr title="inglese">EN</abbr></span>) <a rel="nofollow" class="external text" href="https://www.britannica.com/topic/vertex"><span style="font-style:italic;">vertex</span></a>, su <span style="font-style:italic;"><a href="/wiki/Enciclopedia_Britannica" title="Enciclopedia Britannica">Enciclopedia Britannica</a></span>, Encyclopædia Britannica, Inc.</cite> <span class="mw-valign-text-top noprint" typeof="mw:File/Frameless"><a href="https://www.wikidata.org/wiki/Q1304193#P1417" title="Modifica su Wikidata"><img alt="Modifica su Wikidata" src="//upload.wikimedia.org/wikipedia/commons/thumb/7/73/Blue_pencil.svg/10px-Blue_pencil.svg.png" decoding="async" width="10" height="10" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/73/Blue_pencil.svg/15px-Blue_pencil.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/73/Blue_pencil.svg/20px-Blue_pencil.svg.png 2x" data-file-width="600" data-file-height="600" /></a></span></li> <li><cite id="CITEREFMathWorld" class="citation web" style="font-style:normal">(<span style="font-weight:bolder; font-size:80%"><abbr title="inglese">EN</abbr></span>) Eric W.
