Mutual recursion is very common in functional programming, and is often used for programs written in LISP, Scheme, ML, and similar programming languages. For example, Abelson and Sussman describe how a meta-circular evaluator can be used to implement LISP with an eval-apply cycle. [7] In languages such as Prolog, mutual recursion is almost ...

The MIT School of Engineering (SoE) is one of the five schools of the Massachusetts Institute of Technology, located in Cambridge, Massachusetts, United States. It was established in 1932 as part of the reorganization of the Institute recommended by President Karl Taylor Compton.
With approximately 180 faculty members, 337 graduate students, 130 undergraduate majors, 161 undergraduate minors, the school is the fourth largest at MIT. 3 Nobel Laureates, 8 MacArthur Fellows, and 5 Pulitzer Prize winners are on the faculty. [8]
This mutually recursive definition can be converted to a singly recursive definition by inlining the definition of a forest: t: v [t[1], ..., t[k]] A tree t consists of a pair of a value v and a list of trees (its children). This definition is more compact, but somewhat messier: a tree consists of a pair of one type and a list another, which ...
Anonymous recursion primarily consists of calling "the current function", which results in direct recursion. Anonymous indirect recursion is possible, such as by calling "the caller (the previous function)", or, more rarely, by going further up the call stack, and this can be chained to produce mutual recursion.
The Y combinator allows recursion to be defined as a set of rewrite rules, [21] without requiring native recursion support in the language. [22] In programming languages that support anonymous functions, fixed-point combinators allow the definition and use of anonymous recursive functions, i.e. without having to bind such functions to identifiers.
The MIT School of Science is one of the five schools of the Massachusetts Institute of Technology, located in Cambridge, Massachusetts, United States.The School, which consolidated under the leadership of Karl Taylor Compton in 1932, is composed of 6 academic departments who grant SB, SM, and PhD or ScD degrees; as well as a number of affiliated laboratories and centers.
