Covering the complete graph by partitions

Efficient Covering Designs of the Complete Graph

Let H be a graph. We show that there exists n0 = n0(H) such that for every n ≥ n0, there is a covering of the edges of Kn with copies of H where every edge is covered at most twice and any two copies intersect in at most one edge. Furthermore, the covering we obtain is asymptotically optimal.

Eecient Covering Designs of the Complete Graph

Let H be a graph. We show that there exists n 0 = n 0 (H) such that for every n n 0 , there is a covering of the edges of K n with copies of H where every edge is covered at most twice and any two copies intersect in at most one edge. Furthermore, the covering we obtain is asymptotically optimal.

Packing and covering the complete graph with cubes

A decomposition of Kn \L, the complete graph of order n with a subgraph L (called the leave) removed, into edge disjoint copies of a graph G is called a maximum packing of Kn with G if L contains as few edges as possible. A decomposition of Kn U P, the complete graph union a graph P (called the padding), into edge disjoint copies of a graph G is called a minimum covering of Kn with G if P conta...

Computing Graph Properties by Randomized Subcube Partitions

We prove a new lower bound on the randomized decision tree complexity of monotone graph properties. For a monotone graph property $A$ of graphs on $n$ vertices, let $p=p(A)$ denote the threshold probability of $A$, namely the value of $p$ for which a random graph from $G(n,p)$ has property $A$ with probability $1/2$. Then the expected number of queries made by any decision tree for $A$ on such ...
