Abstract: Methods, systems, and articles of manufacture utilizing the biological principle of dominance to affect the operation of a genetic algorithm are provided. The genetic algorithm may be used to select a multi-parameter solution set to a user-defined problem, with each parameter modeled as a gene. Dominance may be introduced by associating a dominance attribute with one or more gene values (i.e., traits), for example, that are known to lead to good solution sets, allowing the corresponding gene values to be specified as dominant or recessive. By specifying the known good gene values as dominant, system performance may be optimized as the genetic algorithm may quickly arrive at a good solution set (e.g., due to the known good value appearing more often in future generations). On the other hand, by specifying the known good gene value as recessive, the search space may be increased as the genetic algorithm may evaluate a larger number of possible solution sets (e.g.

Abstract: A sealed radial rolling bearing, particularly for use as a supporting or curve roller, comprising race rings arranged concentrically in each other with mutually facing raceways between which cylindrical rolling elements roll, a flanged wheel of angular cross-section being provided at least one axial end of the inner ring for the axial guiding of the rolling elements, wherein the axial leg of the flanged wheel is fitted on the outer peripheral surface of the inner ring under radial pre-tension and a part of the outer periphery of the flanged wheel forms a counter-surface for a seal arranged on the outer ring, characterized in that the inner ring has a smooth cylindrical periphery surface and the radial leg of the flanged wheel bears against the front face of the inner ring.
