0 the practice of describing numbers, expressions, etc. in terms of the numbers, expressions, etc. that come before them in a series:
Recursion allows humans to link various parts of our experience.
The idea that recursion is an essential property of human language has been challenged recently.
Recursion involves embedding an expression of some type within an expression of the same type.
Here, applying simple recursions, h1t u !
The recursions describing the time path of bt are the same for both models, except for the value of the positive definite matrix modifying the forecast error.
The semantics of the language is based on a translation, and it exploits abstract data types rather than polymorphic types and recursion.
The structural aspect of recursion is almost ignored and certainly never presented as the bridge to object-oriented programming.
The programmer sees only recursion equations, but the machine performs normal order graph reduction using those equations as rules.
