Exploring the tree of numerical semigroups In this paper we describe an algorithm visiting all numerical semigroups up to a given genus using a well-suited representation. The interest of this algorithm is that it fits particularly well the architecture of modern computers allowing very large optimizations: we obtain the number of numerical semigroups of genus $gleq 67$ and we confirm the Wilf conjecture for $gleq 60$.
