Of course, there exist well--known methods for computing (co)homology groups, for example, the reduction algorithm consisting in reducing the matrices corresponding to the differential in each dimension to the Smith normal form, from which one can read off (co)homology groups of the complex, or the incremental algorithm (due to Edelsbrunner et al.) for computing Betti numbers. However, there is a gap in the literature concerning general methods for computing cohomology operations.
