HIP, a set of computer packages for symbolic calculation of Feynman diagrams, is presented. The packages were designed as an aid in calculating tree‐level multiparticle electroweak production processes, though they can be used for a much wider class of calculations. The packages have been used to calculate such processes as eγ→Wν and γγ→W + W − at tree level with arbitrary Wγ couplings. The packages are written in the computer algebra language M a t h e m a t i c a, which provides a powerful working environment.

An analysis of numerical simulation codes from an abstract point of view suggests some structure common to most if not all codes. PANACEA, a practical application of such an analysis, constitutes a significant tool to facilitate building portable, efficient simulation codes with sharable modules and to provide built‐in support for problem generation and visualization of simulation results.
