An easy subexponential bound for online chain partitioning

Data Structures and Algorithms 2018-04-17 v2 Combinatorics

Abstract

Bosek and Krawczyk exhibited an online algorithm for partitioning an online poset of width ww into w14lgww^{14\lg w} chains. We improve this to w6.5lgw+7w^{6.5 \lg w + 7} with a simpler and shorter proof by combining the work of Bosek & Krawczyk with work of Kierstead & Smith on First-Fit chain partitioning of ladder-free posets. We also provide examples illustrating the limits of our approach.
