Nature of problem:
Efficient, robust and automatic numerical computation of multidimensional integrals with singular integrands, for example occurring in the calculation of particle scattering amplitudes in perturbative field theory.
Runtime- or memory-optimised algorithms that combine integration rule and Monte Carlo techniques and employ recursion.
singint_rec, the implementation of the recursive algorithm, is suitable for integrands of up to 12 dimensions. singint_cut, the implementation of the global algorithm, is currently restricted to two dimensions. An extension of the algorithm to more than two dimensions is straightforward and will be implemented in a future version.
SINGINT can be built with any compatible C and Fortran compilers. It requires GNU Scientific Library 1.2 . The program has been tested with GNU Compiler Collection 3.1  on Red Hat Linux 7.1.
