Abscissa and ordinate 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). Usually these are the horizontal and vertical coordinates of a point in a two-dimensional rectangular Cartesian coordinate system. The terms can also refer to the horizontal and vertical axes respectively (typically "x"-axis and "y"–axis) of a two-dimensional graph. An ordered pair consists of two terms—the abscissa (horizontal, usually "x") and the ordinate (vertical, usually "y")—which define the location of a point in two-dimensional rectangular space. Though the word "abscissa"
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
