The algorithm implemented in form of a C++ code closely follows the method by Ellis, Giele, Kunszt and Melnikov. For the case of gluons, the algorithm is briefly reviewed. Double-precision results are presented documenting the accuracy and efficiency of this computation.Contribution to Proceedings of LCWS08 and ILC08High Energy Physics - Phenomenologytext
