Abscissa and ordinate Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative; after: positive). The ordinate of a point is the signed measure of its projection on the secondary axis, whose absolute value
Biased random walk on a graph on a graph has attracted the attention of many researchers and data companies over the past decade especially in the transportation and social networks. There have been written many different representations of the biased random walks on graphs based on the particular purpose of the analysis. A common representation of the mechanism for undirected graphs is as follows: On an undirected graph, a walker takes a step from the current node, formula_1 to node formula_2 Assuming that each node has an attribute formula_3 the probability of jumping from node formula_4 to formula_5 is given by: where formula_7 represents the topological
