specialization spe·cial·i·za·tion (spěsh'ə-lĭ-zā'shən)
The act of specializing.
Adaptation, as of an organ or organism, to a specific function or environment.
A reduction in generality, usually for the sake of increased efficiency. If a piece of code is specialised for certain values of certain variables (usually function arguments), this is known as "partial evaluation". In a language with overloading (e.g. Haskell), an overloaded function might be specialised to a non-overloaded instance at compile-time if the types of its arguments are known.
