Abstract
An extension of the SARGE algorithm of
van Hameren, Kleiss and Draggiotis
is introduced,
which includes the incoming momenta in the kinematical pole structure
of the
density with which the momenta are generated. The algorithm is
compared with
RAMBO in the integration of QCD amplitudes in the SPHEL approximation,
and
the computing times are extrapolated to those for the calculation
with exact
matrix elements.
