real-coded
1.The choosing, crossing and variation operation are improved using real-coded schema.
2.The classical real-coded genetic algorithm (RGA) is analyzed. On this foundation, aimed at the deficiency existing, the improved real-coded genetic algorithm (IRGA) is proposed, which has self-adaptable mutation operator and multi-turns evolution strategy.
4.Described was a design of a serial real-time clock chip with I2C bus interfaces,which was a low power,full binary-coded decimal(BCD) clock/calendar chip,and whose address and data were transferred serially through an I2C bidirectional bus.
