The Neighbourhood Polynomial of some Nanostructures
The neighbourhood polynomial G , is generating function for the number of faces of each cardinality in the neighbourhood complex of a graph. In other word $N(G,x)=sum_{Uin N(G)} x^{|U|}$, where N(G) is neighbourhood complex of a graph, whose vertices are the vertices of the graph and faces are subsets of vertices that have a common neighbour. In this paper we compute this polynomial for some na...
متن کاملSAC and neighbourhood SAC
This paper introduces a new kind of local consistency based on the general idea of singleton arc consistency (SAC). This is a reduced form of SAC that only considers neighbourhoods of a variable with a singleton domain; hence, the name “neighbourhood SAC” (NSAC). Like AC and SAC, NSAC has a unique fixpoint, so that NSAC algorithms will produce the same result when applied to a problem regardles...
متن کاملNeighbourhood, family and health care.
OBJECTIVE The effects of family and place on health outcomes may be seriously misestimated by standard analytic techniques. The information-rich settings in several Canadian provinces can provide appropriate designs to minimize biases resulting from omitted variables and measurement error. This paper compares siblings with children living in the same neighbourhood (but not in the same family) i...
