FORCE-DIRECTED GRAPHS

摘要

Embodiments of the present invention provide systems and methods for graphing networks. In one embodiment, a dampening heuristic is utilized to graph networks to increase their stability. Nodes are visualized by finding local and global minima and equilibrium positions. Factors such as the influence of neighboring nodes; attraction and repulsion phases; and dynamism of complex networks are addressed by embodiments of the present invention. The stability of nodes are measured quantitatively using vectors, degree of influence of neighboring nodes on other nodes, and updating dampening heuristics.

1. A computer program product for visualizing elements of a graph of a set of at least two nodes, the computer program product comprising:
a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising: responsive to combining a set of attractive forces and a set of repulsive forces of the set of at least two nodes, program instructions to generate a set of new node positions; program instructions to determine a position of the set of at least two nodes is based on a set of vectors of the set of at least two nodes, wherein each node is a common point to the set of vectors and is associated with an angle; program instructions to calculate a relative stability value of a first node of the set of at least two nodes based on a dampening heuristic, wherein the dampening heuristic is based on: a degree of nodes, any variations in vector magnitude due to non-resting states and to fluxional stability of the at least two nodes, and any changes in the set of attractive forces and the set of repulsive forces of the set of at least two nodes; program instructions to assess a position of the set of at least two nodes as either a global minimum, a local minimum, or an equilibrium; and program instructions to display the set of at least two nodes in the graph by linking at least two nodes from the set of new node positions with an edge, based, at least in part, on: the set of attractive forces and the set of repulsive forces, a distance, and the relative stability value determined to be above a threshold value.
