  We have developed an efficient algorithm for the subtraction of infrared
divergences that arise in the evaluation of QED corrections to the anomalous
magnetic moment of lepton (g-2). By incorporating this new algorithm, we have
extended the automated code-generating system developed previously to deal with
diagrams without internal lepton loops (called q-type), which produced
convergent integrals when applied to diagrams that have only
ultraviolet-divergent subdiagrams of vertex type. The new system produces
finite integrals for all q-type diagrams, including those that contain
self-energy subdiagrams and thus exhibit infrared-divergent behavior. We have
thus far verified the system for the sixth- and eighth-order cases. We are now
evaluating 6354 vertex diagrams of q-type that contribute to the tenth-order
lepton g-2.
