Parameter adjusting device

Abstract

A parameter adjusting device optimizes parameters using a genetic algorithm by using a plurality of processing devices. The plurality of processing devices is respectively configured to individually and simultaneously execute the genetic algorithm and to, a predetermined period prior each local search, be such that each processing device, in accordance with the genetic algorithm processing, based on predetermined numbers, send individuals of a genetic population to others of the plurality of processing devices and further configured to have a migration arrangement for receiving the predetermined numbers.

1 . A parameter adjusting device for optimizing parameters using a genetic algorithm by using a plurality of processing devices, wherein said plurality of processing devices is respectively configured to individually and simultaneously execute the genetic algorithm and to, a predetermined period prior each local search, be such that each processing device, in accordance with the genetic algorithm processing, based on predetermined numbers, send individuals of a genetic population to others of said plurality of processing devices and further configured to have a migration arrangement for receiving the predetermined numbers. 
   
   
       2 . The parameter adjusting device as set forth in  claim 1 , wherein the each processing device comprises a CPU of a computer or server including a plurality of CPUs in which said genetic algorithm is installed. 
   
   
       3 . The parameter adjusting device as set forth in  claim 1 , wherein the migration arrangement transfers individual information to be migrated, along a ring shape route. 
   
   
       4 . The parameter adjusting device according to  claim 1 , wherein a selected one of the plurality of processing devices is configured to determine if all of the searches conducted by the plurality of processing devices have been completed and to terminate the local search process in response to completion of all local searches.
