</ul>
<p>さらに、隣接リストで頂点を表現するために<code>Vertex</code>クラスを使用します。その理由は：隣接行列のようにリストインデックスを使用して異なる頂点を区別する場合、インデックス<span class="arithmatex">\(i\)</span>の頂点を削除したい場合、隣接リスト全体を走査し、<span class="arithmatex">\(i\)</span>より大きいすべてのインデックスを1つずつ減少させる必要があり、これは非常に非効率的です。しかし、各頂点が一意の<code>Vertex</code>インスタンスである場合、頂点を削除しても他の頂点に変更を加える必要がありません。</p>
