This paper contains a survey of numerical methods for connecting orbits in discrete dynamical systems. Special emphasis is put on degenerate cases where either the orbit. loses transversality or one of its endpoints loses hyperbolicity. Numerical methods that, approximate the connecting orbits by finite orbit sequences are described in detail and theoretical results on the error analysis are provided. For most of the degenerate cases we present examples and numerical results that, illustrate the applicability of the methods and the validity of the error estimates.
