だから、掘り下げて別のものを試してみたら、ここで私が思いついたのは私のために働くものです。 salutionはいくぶん複雑で、冗長バスは明らかに正確な結果を与えます。答えを見つけようとすると、ベクタライズされたコードを生成すると、結果を約3分に短縮したのに対し、完成せずに約96時間後に計算を停止する前に、ベクトル化の煩わしさ(私のドイツ語のアクセントを赦免すること)を学びました。
文書化された日付のリスト(すべての医師が自分のシフトの文書を完成させるわけではありません)は、簡単な日付のExcelシートです。文書化された時間の作業間隔のリストは、誰かがあるコラムで患者を見るのを開始し、その患者を別のコラムで見ることをやめた日時である。次の行は、開始時刻と終了時刻が似ています。
テキスト中のすべての変数はドイツ語またはドイツ語の略語ですが、私のコメントが何が起こっているのかを理解するのに十分であることを願っています。また、多くのコードは私の状況に固有の問題のためのものです。
ソリューションのさまざまな面で私を助けたユーザーPhiSeuとuser3507085に感謝します。
