Generic Programming is a programming paradigm for developing efficient, reusable software libraries. Pioneered by Alexander Stepanov and David Musser, Generic Programming obtained its first major success when the Standard Template Library became part of the ANSI/ISO C++ standard. Since then, the Generic Programming paradigm has been used to develop many generic libraries.

The Generic Programming process focuses on finding commonality among similar implementations of the same algorithm, then providing suitable abstractions in the form of concepts so that a single, generic algorithm can realize many concrete implementations. This process, called lifting, is repeated until the generic algorithm has reached a suitable level of abstraction, where it provides maximal reusability without sacrificing performance. Dual to the lifting process is specialization, which synthesizes efficient concrete implementations for particular uses of a generic algorithm. Only by balancing the lifting and specialization processes can we ensure that the resulting generic algorithms are both reusable and efficient.
