  1. 10563: Least Squares • ★★★☆☆ • 題組:Problem Set Archive with Online Judge • 題號:10563: Least Squares • 解題者:王耀頡 • 解題日期:2011年4月13日 • 題意:給一個矩陣大小m(<=100)和n(<=80)以及一不規則的圖形 (‘?’表圖形部分而 ‘.’表示非圖形之空白區),然後用各種大小的正方形完整地覆蓋它,以蠟筆著色的方式,顏色以A~Z表示並且相鄰兩正方形不得同色,而輸出所形成的字串能在字序中首次出現。

  2. 題意範例: m=5 n=5            ?????            .???. .???.            .???.            ?????    ABBBA      ABAAB    .BBB.      .CAA.    .BBB.      .ABB.    .AAC.      .CBB.    BAABC      ABACA

  3. 解法:先設為A若有相鄰的與原色相同就+1變成B直到無相鄰同色,再看後一個的最小可能值,若沒有比原位置的字元小,則開始擴張領土,以裹棉被的方式擴張,每加一層,就要判斷一次顏色的重複以及圖形上的?和. 直到碰到不符合者跳出迴圈,繼續尋找未著色區域到圖形最後結束。 • 解法範例:無 • 討論:無
