The average orientable genus of graphs has been the subject of a considerable number of recent investigations. It is the purpose of this article to examine the extent to which the average genus of the amalgamation of graphs fails to be additive over its constituent subgraphs. This discrepancy is bou

โฆ Synopsis
Two lower bounds are obtained for the average genus of graphs. The average genus for a graph of maximum valence at most 3 is at least half its maximum genus, and the average genus for a 2-connected simplicial graph other than a cycle is at least 1/16 of its cycle rank.

A channel graph is the union of all paths between a given input and a given output in an interconnection network. At any moment in time, each vertex in such a graph is either idle or busy. The search problem that we consider is to find a path (from the given input to the given output) consisting ent
## Abstract For any graph __G__, let __i__(__G__) and ฮผ;(__G__) denote the smallest number of vertices in a maximal independent set and maximal clique, respectively. For positive integers __m__ and __n__, the lower Ramsey number __s__(__m, n__) is the largest integer __p__ so that every graph of or
We show lower bounds on the worst-case complexity of Shellsort. In particular, ลฝ ลฝ 2 . ลฝ . 2 . we give a fairly simple proof of an โ n lg n r lg lg n lower bound for the size of Shellsort sorting networks for arbitrary increment sequences. We also show an identical lower bound for the running time o
We consider the exploration of random digraphs. We give upper and lower bounds for the expected number of edges traversed during an exploration. This result implies a lower bound for the expected running time of a wide class of algorithms, e.g., breadth-first-search, depth-first-search, and algorith
## Abstract We compute the following upper bounds for the maximal arithmetic genus __P~a~(d,t__) over all locally Cohen โ Macaulay space curves of degree __d__, which are not contained in a surface of degree magnified image These bounds are sharp for t โค 4 abd any d โฅ t.
