Summary: We are going to analyze simple search tree algorithms for approximating \(d\)-Hitting Set, focussing on the case of factor-2 approximations for \(d = 3\). We also derive several results for hypergraph instances of bounded degree, including a new polynomial-time approximation.
For the entire collection see [Zbl 1241.68041].
