Keywords: Unitarity method, One-loop corrections.
PACS: 12.38.bx, 12.38.-t.
Classification: 11.5.

External routines: QCDLoop (http://qcdloop.fnal.gov/), qd (http://crd.lbl.gov/~dhbailey/mpdist/)

Nature of problem:
Evaluation of next-to-leading order corrections for gluon scattering amplitudes in pure gauge theory.

Solution method:
Purely numerical approach based on tree amplitudes obtained via Berends-Giele recursion combined with unitarity method.

Restrictions:
Running in double precision the number of gluons should not exceed 14

Running time:
Depending on the number of external gluons between less than a milli second (4 gluons) up to a 1s (14 gluons) per phase space point.
