Grammar & Patterns(句型)

What are common sentence patterns for "Algorithm"?How to make natural sentences with "Algorithm"?
PatternMeaningExample
algorithm + for + V-ing/noun用於…的演算法The company developed a new algorithm for detecting fraud. (該公司開發了一種用於偵測詐欺的新演算法。)
algorithm + to + V用來…的演算法We need a more efficient algorithm to sort the data. (我們需要一個更有效率的演算法來排序資料。)
implement/use + an + algorithm實行/使用演算法The software uses a complex algorithm to generate recommendations. (該軟體使用一個複雜的演算法來產生推薦。)
develop/design + an + algorithm開發/設計演算法She spent months designing the algorithm. (她花了數月時間設計這個演算法。)
run/execute + an + algorithm執行/運算演算法The computer will run the algorithm overnight. (電腦將在夜間執行這個演算法。)

用法說明

How is "Algorithm" different from similar structures?What usage mistakes are common with "Algorithm"?

algorithm for + V-ing vs. algorithm to + V

  • algorithm for + V-ing 強調演算法的「目的或功能」,說明它是用來處理某個特定動作或任務的。
  • algorithm to + V 強調演算法的「能力或設計目標」,說明它能夠或旨在完成某個動作。
  • 在許多情況下,兩者可以互換,但細微差別在於 for V-ing 更偏向描述用途,而 to V 更偏向描述意圖。
  • 當描述一個已存在、用於解決已知問題的演算法時,for V-ing 很常見。當描述一個新設計或理論上能達成某目標的演算法時,to V 也很自然。 EN: This is a classic algorithm for sorting large datasets. 翻譯: 這是一個用於排序大型資料集的經典演算法。

EN:They developed a new algorithm to optimize the network traffic.

翻譯:他們開發了一種新的演算法來優化網路流量。

總結建議

一般情況下兩者皆可,若強調具體「用途」可用 for V-ing,強調「設計目標」或「能力」則用 to V

易混淆對比

What is the difference between "Algorithm" and similar words?How to choose "Algorithm" vs alternatives?

algorithm vs formula

algorithm 是一系列解決問題的步驟,強調過程與邏輯;formula 是固定的數學表達式或化學式,強調計算結果。

algorithm vs process

algorithm 是精確定義、可重複執行的計算步驟;process 是更廣泛的活動或程序,可能包含人為判斷或非計算步驟。

algorithm vs heuristic

algorithm 保證在有限步驟內得到正確或最優解;heuristic 是經驗法則,追求在合理時間內找到足夠好的解,但不保證最優。

EN:The whole algorithm needs to be rethought from scratch.

翻譯:整個 algorithm 都需要從頭重新思考。
