翻轉教室 (Flipped classroom)

方式：

• 上課前看完影片，做筆記，總結重點。看一下相關的習題，想一下在哪一節，如何做？
• 只寫標題不是總結重點，例如報童模型、隨機過程、決策準則、轉移機率。
• 好的例子
• 空間分佈等候線：服務時間不是指數函數分配，且有上下限。
• 動態規劃:由終點往起點計算 (Backward in time)  動態；當存貨水平不同，價格會變化。針對每周、所有存貨水平、先前價格...所以動態規劃在這裡可以得出最佳解。
• 流量平衡方程式：進一定會等於出。三種形式。所有的機率和一定等於一。

失敗為成功之母？

有時候，很努力也不一定會有成果。

心情低落了好幾天，喝點小酒和親友聊聊天，轉換心情。

出版論文驚魂記

因為決策樹和最佳化的進展，所以想要把它用來解決生產製造的問題。

花了一年多、寫了數千行的程式，萃取出成功的部分結果，投稿到第一個期刊，被退稿。
