Factor is a stack-oriented programming language created by Slava Pestov. Factor is dynamically typed and has automatic memory management , as well as powerful metaprogramming features. The language has a single implementation featuring a self-hosted optimizing compiler and an interactive development environment .
The higher the branching factor, the faster this "explosion" occurs. The branching factor can be cut down by a pruning algorithm. The average branching factor can be quickly calculated as the number of non-root nodes (the size of the tree, minus one; or the number of edges) divided by the number of non-leaf nodes (the number of nodes with ...
An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
This is a "genealogy" of programming languages.Languages are categorized under the ancestor language with the strongest influence. Those ancestor languages are listed in alphabetic order.
Richard C. Johnson et al. (1994) proposed a program structure tree (PST), a hierarchical representation of program structure based on single edge entry and single edge exit regions. [5] [6] The PST can be computed in (| |) time for an arbitrary flow graph, where is the set of edges in the graph. The disadvantage of the PST is that it exploits ...

Often trees have a fixed (more properly, bounded) branching factor , particularly always having two child nodes (possibly empty, hence at most two non-empty child nodes), hence a "binary tree". Allowing empty trees makes some definitions simpler, some more complicated: a rooted tree must be non-empty, hence if empty trees are allowed the above ...
In functional programming, fold (also termed reduce, accumulate, aggregate, compress, or inject) refers to a family of higher-order functions that analyze a recursive data structure and through use of a given combining operation, recombine the results of recursively processing its constituent parts, building up a return value.
