摘要： A method and system for sorting count information in a computer. Frequencies of usage of count information to be sorted are determined, accumulation information are prepared based on the frequency of usage information. Regarding the accumulation information as the post-sort sequence information, the post-sort information is prepared by using the post-sort sequence information and implementation of the post-sort sequence information.The frequency of usage information designates the write position of the post-sort sequence information and sorts the count information in the ascending or descending order.

摘要： There is provided a placement optimization system for determining layout in printed circuits and semiconductor substrates, comprising input means for inputting circuit connection information, placement optimization means for deriving wiring density distribution on the basis of the circuit connection information, evaluating the height and/or width of the wiring region statistically estimated from the wiring density distribution, and output means for outputting the resultant placement position information. Further, the placement optimization system may comprise means for collecting placement elements into sets, determining placement of the sets, then developing the sets into elements, and determining optimum placement positions of the elements.

摘要： During an optimization of an organization of mutually-related elements, an element organization is gradually changed toward an objective specification by local changes of the element organization. A value of an objective function depends on a degree of a nearness of the element organization to the objective specification. A redundancy function of a number of elements in an improvement group is determined in consideration of a fluctuation in the value of the objective function, so that suitable changes of the improvement group are performed by use of the definite redundancy. An intermediate element organization is rejected and accepted in accordance with the redundancy function value, so that a final element organization can be obtained in consideration of a global aspect of the element organization.
