Nature of problem:
Systematic expansion of higher transcendental functions in a small parameter. The expansions arise in the calculation of loop integrals in perturbative quantum field theory.

Solution method:
Algebraic manipulations of nested sums.

Usually limited only by the available disk space.

Running time:
Dependent on the complexity of the problem.
