We discuss algebraic/numeric methods to compute one-loop corrections for
multiparticle/jet production cross sections. By using efficient reduction
algorithms a compact expression for the ggg\gamma\gamma -> 0 amplitude is
obtained. Further a numerical approach for 6-point 1-loop diagrams is
presented.
