Abstract
This paper studies algorithmic Helly-type problems in the framework of the algorithmic theory of convex bodies developed by Grotschel, Lovas z, and Schrijver. Various oracle-polynomial-time algorithms are presen ted that are complemented by NP-hardness results for polytopes. In add ition, some new Helly-type theorems are derived.
