The authors study SU(2) Yang-Mills gauge fields of a 4-dimensional simplicial lattice. They present an algorithm which computes the second Chern number (the topological charge) of the corresponding principal bundles directly from the lattice data. This algorithm only involves evaluation of \(4\times 4\) determinants and the solution of quadratic equations.
