书籍介绍
这不是一本教你怎么写代码的书,而是带你追问“计算”究竟是什么。塞普斯把目光从图灵机的繁琐编程上移开,让图灵机只作为一个严谨的“模型”存在,真正的主角是算法本身。全书以“证明思路”代替机械推演,用自然语言而非伪代码讲述算法,迫使读者去 grasp 形式化符号背后的思想,而非陷于技术细节。读者普遍反馈:它难,上得很累,但读完有种“打通任督二脉”的畅快感——有人称其为“计算科学的九阳神功”,也有人读完后才意识到经典《自动机理论》的枯燥。它适合愿意啃原理、渴望建立计算全景观的人,也适合想弄清“可计算性边界”与“为何有些问题本质上无解”的求索者。
精彩摘录
  • "Ignoring the trees to see the forest doesn't mean that one is more important than the other--it just gives a different perspective."
  • "We have come to a turning point in the study of the theory of computation. We continue to speak of Turing machines, but our real focus from now on is on algorithms. That is, the Turing machine merely serves as a precise model for the definition of algorithm. We skip over the extensive theory of Turi"
