WitrynaAlgorithm (Hertl & Mehlhorn): Start with a triangulation and remove inessential diagonals. Claim: This algorithm is never worse than 4×optimal in the number of convex pieces. Convex Partitions (by Diagonals) Proof: When the algorithm terminates, every remaining diagonal is essential for some (reflex) vertex. Each reflex vertex can have …
