    Abstract: PROBLEM TO BE SOLVED: To generate a uniformly distributed discrete pattern.SOLUTION: An information processing device 100, for calculating a spatial arrangement of plural elements of a discrete pattern formed by the elements spatially discretely arranged, calculates, for each element, a density at initial positions respectively given to the individual elements on the basis of density distribution of the elements within a region where the elements of the discrete pattern are arranged, to set a diagram having a size in accordance with the density and representing a region in which the individual elements reject others and the moving range of the diagram at the initial positions of the individual elements, and minimizes a target function to give a penalty to a mutual collision of diagrams and protrusion of a diagram from the moving range, using the respective positions of the individual diagrams as decision variables to calculate the optimum solution of the respective positions of the individual diagrams and output the resultant optimum solution of the respective positions of the individual diagrams as the spatial positions of the elements.

    Abstract: Likely disconnections or system-level-impact producing slowdown in a flow parameter in a network can be identified by annotating a graph representing the network with a weight to edges of a graph representing the network. The weight can be linearly or non-linearly proportional to the inverse of the severity of the impact, and/or linearly or non-linearly proportional to the inverse of the likelihood of disconnection. Minimal cut sets needed to generate a disconnection in the network are identified from the annotated network based on the weights on the edges. Subsets of each minimal cut set are generated and evaluated during a simulation. The subsets can correspond to almost isolated scenarios for the network. The scope of the simulations can be reduced by selecting the minimal cut sets employing the weight.
