The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it's often poorly taught and clarifying the fundamental principles of all recursive algorithms. You'll learn when to use recursive functions (and, most importantly, when ...

Recursion is used very commonly in programming, although many simple examples (including some shown in this section) are actually not very efficient and can be replaced by iterative methods (loops or vectorized code in MATLAB). Nontrivial examples go beyond the scope of this book, so the ...
code into a visual tree for clarity. Known as a "top-down parser," a recursive descent parser reads the input from left to right in contrast to a "bottom-up parser" (such as a shift-reduce parser) that starts with the right side of a grammatical entity. SeeXML,parseandrecursion. ...

与Sacks 的higher recursion theory互相补充 这本书可以作为Sacks 的"higher recursion theory"第一部分的后续。作者是集合论学家,因此书中的方法基本是集合论和模型论的。因此读者如果对Higher recursion theory有了一定了解,建议用递归论方法把这些结论重新证明一遍。这本书的好处是给出了几个非常重要的定理的证明。
Explore book DEFINITION 2.3.1 (Recursion) We assume a set of recursion variables {Xj | j∈ J} for some index set J. A recursive specification E is a set of recursive equations Xj = Tj for j∈ J, where Tj is an ACP(A, |, τ)-term in which the recursion variables Xi for i∈ ...
(Ifz≤ 0 the functionf[n] is basically not defined, because the recursion is trying to computef[n] fromf[n],f[n+ 1], etc., so never “makes progress”.) The casef[0] = 2 (i.e.z= 2) is the one that involves the least lookback—and a total of 3 initial values. Here ...
the book emphasizes the logic of the feedback loop or ‘recursion’, showing how it drives multiple Russian performances of national belonging and nation projection in the digital era. It applies this theory to recent issues, events, and scandals that have played out in international arenas rangin...
We add a recursion for the derivative of the type: f′(z1) = w′1w1′ and f′(zn+1) = a′nan′ [(1 − |zn|2)/(1 − |zn+1|2)] f′(zn) + w′n+1,wn+1′, where (a′nan′) is bounded and (w′nwn′) is an appropriate sequence, and we also look for zero-...
