    abstract = {This paper studies algorithmic Helly-type problems in the framework of the algorithmic theory of convex bodies developed by Grötschel, Lovász, and Schrijver. Various oracle-polynomial-time algorithms are presented that are complemented by NP-hardness results for polytopes. In addition, some new Helly-type theorems are derived.},
