Nick Szabo -- Introduction to Algorithmic Information Theory

by ogrisel (via)
Recent discoveries have unified the fields of computer science and information theory into the field of algorithmic information theory. This field is also known by its main result, Kolmogorov complexity. Kolmogorov complexity gives us a new way to grasp the mathematics of information, which is used to describe the structures of the world. Information is used to describe the cultural structures of science, legal and market institutions, art, music, knowledge, and beliefs. Information is also used in describing the structures and processes of biological phenomena, and phenomena of the physical world. The most obvious application of information is to the engineering domains of computers and communications. This essay will provide an overview of the field; only passing knowledge of computer science and probability theory is required of the reader.

Graph-based Modeling on Python

by YukuanBlog & 1 other
模擬複雜網路,也可以套用 Agent-based modeling 架構。不過諸如網路的群聚度(clustering coefficient, C)及網路特徵的路經長度(characteristic path length, L)等統計數據計算需耗費的時間,隨著網路的規模成長很快,所以不適合運作太頻繁。但我們卻得靠這些統計數據來判斷網路是否收斂、試驗是否該終止了,想試驗各個參數排列組合時,更是雪上加霜。

六個人的小世界

by YukuanMark
「網路科學」提供了一種不同的思考模式,為古老的問題指引出新的方向。為此,本書融合了兩個故事:首先是關於「網路科學」本身的故事──它從何而來,發展到什麼程度,演進的過程又是如何;其次,是關於疾病蔓延、文化時尚、財務危機、組織創新等真實世界的現象,這些都是網路科學所試圖了解的對象。

小小世界

by YukuanMark
每個人都熟悉所謂“小世界現象”︰當你遇見一個陌生人,交談不久之後,我們往往會驚奇地發現︰“原來我們有共同的朋友!”或者說,僅通過幾個熟識的人,我們就早已經相互聯系在一起了

[心得] Small Worlds

by YukuanBlog
  今天晚上發起狠來,一口氣把天下出的這本《連結》 K 完了。   這裡非常推薦大家真的可以好好地給他瞧一瞧!

[Notes] NEXUS: Small Worlds and the Groundbreaking Science of Networks

by YukuanBlog
好書值得一再推薦,天下出的這本關於小世界的譯作真得非常值得大家關注一下。畢竟數學是各種科學的媽,何況這本書也寫得蠻淺顯的,不看真得很可惜。

《理性之夢》

by YukuanBlog
首先我要先聲明,閱讀本書最好選擇頭腦清晰的時候。如果可能的話,還要來回多讀幾遍,因為其描述的內容廣泛,但卻圍繞著同一個隱約的中心議題。
