Abstract

　カップルドノードツリーはルートノードと、隣接した記憶領域に配置されるブランチノードとリーフノードまたはブランチノード同士またはリーフノード同士のノード対からなる。ブランチノードはビット列検索を行う検索キーの弁別ビット位置とリンク先のノード対の一方のノードである代表ノードの位置を示す位置情報を含む。リーフノードは検索対象のビット列からなるインデックスキーを含む。カップルドノードツリーのノードは深さ優先探索順に退避される。退避された順にノードを読み出し、ノードを復元すべき位置の位置情報をスタックに格納し、ブランチノードが続く間は子ノードを順次復元し、リーフノードが読み出されたらリーフノードを復元して、スタックを遡って次に復元すべきノードを決定する処理の繰り返しにより、カップルドノードツリーは復元される。
