    NKA

    Nonlinear Krylov acceleration of fixed-point and Newton-like methods

    Nonlinear Krylov Acceleration (NKA) is a method for accelerating the convergence of fixed-point (Picard) iterations. Many Newton-like and inexact Newton methods are fixed point iterations. The NKA project provides the canonical implementation of the method for several programming languages. The black-box accelerator is simple to integrate into existing code. Placed in the iteration loop, it observes the sequence of solution updates and replaces them with improved updates using information...

    BP (Bilinear Pairing)

    library for Bilinear Pairing

    A library encapsulating bilinear pairing computation and group computation in the cyclic groups G_1, G_2, G_T. The bilinear pairing is a bilinear, non-degenerate map between G_1 and G_2 to an element in G_T. The users can build complex pairing-based software by the Pairing library without much knowledge of elliptic curves or pairing or number theory. The library is smaller than 57 Kbytes, suitable for hand held devices. The size is only 3.7% of the size of the BPC...

    IsItPrime

    A small, basic, yet powerful and competent primality tester.

    IsItPrime is a powerful, cross-platform, multi-threaded standalone application capable of testing massive numbers in several ways through a highly interactive and easily-understood user interface. As of version 2.0.0, IsItPrime and other NCPrime applications no longer require the Visual C++ 2010 Redistributable for Windows. All NCPrime applications released after 1 November 2012 use the Qt framework and thus require Qt libraries (included) for cross-platform compatibility. IsItPrime is...
