algorithm notes

I am taking notes of computer algorithms in zh-Hant.

These notes are free for non-commercial usage. Acknowledgement is not required but would be appreciated.

Most notes are not well-reviewed. If you find any mistakes, please leave message here.

本站提供演算法教學文章。大家可以自行擷取網頁圖文。不要為非作歹、謀取私利就行了。

本站處於創建階段,內容不夠詳盡周全。若讀者發現錯誤,歡迎利用留言板回報,俾能改正,造福後人。

domain

I give attention to algorithms in computational mathematics (computational graph theory, computational number theory, computational geometry, numerical analysis, ...).

I also give attention to algorithms for multimedia (natural language processing, audio processing, image processing, computer graphics, ...).

本站主要關注這兩個領域:計算數學、多媒體。

計算數學:計算圖論、計算數論、計算幾何、數值分析、……。

多媒體:自然語言處理、聲音處理、影像處理、計算機圖學、……。

這些主題並非主要關注方向:作業系統、編譯器、網路、資料庫、軟體工程、資訊安全、app與網頁開發、資訊系統管理、……。

雖然內容廣泛,也不是全部都得弄懂。若有需要,再來學習。大可不必望著目錄自己嚇自己。

unicode characters for math

This website use Unicode characters with monospaced font for presenting equations and formulas.

Thanks to JetBrains Mono, a monospaced font for source code, our webpages have a better view.

眾所皆知,程式設計使用等寬字體。本站打算繼承這種精神。

想在網頁呈現美觀的數學式子,大家習慣使用MathJax。然而本站並未採用MathJax,而是直接使用純文字。MathJax無法做到等寬排版,而純文字卻可以做到等寬排版(使用等寬字體即可)。

很幸運的,Unicode已經定義大量的數學符號,我們可以直接使用這些數學符號。很不幸的,支援所有數學符號的等寬字體尚未出世,支援所有數學符號的網頁瀏覽器尚未出世,我們經常看到排版醜陋的數學式子。

如果你在本站看到偏移變形的數學符號,不要怨我。當今世界的科技進度就是這樣,我已盡力而為。

I am not being hired and I have no income. I wish billionaires provide at least TW$27,470 per month as my salary. Please email to algorithm.notes@gmail.com.

我的收入來源是三倍券、五倍卷、普發現金。不過不必麻煩大家勞師動眾小額捐款,我等有錢人贊助就好了。希望月薪至少是27470元。請來信algorithm.notes@gmail.com

以前曾經開放小額捐款,不過成效不彰,無法維持生計。
