โฆ Synopsis
Answering a question of Rod1 and Thoma, we show that the Nibble Algorithm for finding a collection of disjoint edges covering almost all vertices in an almost regular, uniform hypergraph with negligible pair degrees can be derandomized and parallelized to mn in polylog time on polynomially many parallel processors. In other words, the nearly-perfect packing problem on this class of hypergraphs is in the complexity class NC.

Let H be a k + 1 -uniform, D-regular hypergraph on n vertices and let H be the minimum number of vertices left uncovered by a matching in H. C j H , the j-codegree of H, is the maximum number of edges sharing a set of j vertices in common. We prove a general upper bound on H , based on the codegree
