Abstract: An object is to provide a system in which components can overall operate in concert with one another by using only functions about the components, without using the theory of probability. The system includes a plurality of function blocks correlated to one another.

Abstract: An information representation method for representing an object or a shape includes: dividing a contour shape of an entirety or a part of the object or the shape into one or a plurality of curves; and representing the contour shape of the object or the shape by parameters including a degree of curvature and a positional relationship of each curve obtained by the dividing. Therefore, there is provided an information representation method for an object or a shape, which is capable of robust object recognition against a change in image by geometric transformations and occlusions.

Abstract: A start node acquires coupled state information indicating a connectibility of nodes from a network. By executing simulation in accordance with a computational model constructed based on the coupled state information, the start node determines for each node a first link that transmitted an oscillation or a signal first to the node. A path that extends from a target node to the start node via the first link of intermediate nodes is selected.
