ABSTRACT
Passing functions and function objects to general purpose routines is a powerful abstraction mechanism that should be taught in freshman computer science. In C++, a "function" can be defined directly by the user or by a library or can be defined indirectly via operator() as a member function of a class. It is not obvious how to treat these "functions" in a uniform manner. We will show how function templates in C++ provide an elegant and teachable mechanism for passing entities with functional behavior as arguments to other functions.

RBF neural network based on q-Gaussian function in function approximation
To enhance the generalization performance of radial basis function (RBF) neural networks, an RBF neural network based on a q-Gaussian function is proposed. A q-Gaussian function is chosen as the radial basis function of the RBF neural network, and a ...
The function concept in C++: an empirical study
WGP '09: Proceedings of the 2009 ACM SIGPLAN workshop on Generic programmingHigher-order functions are essential for generic programming. While they are naturally supported in functional programming languages, there are no higher-order functions in C++. There, various function datatypes exist that simulate the effect of higher-...
