Combinational Circuits Evolutionary Impact Analysis in Different Initially Chromosome Codes Scales

Combinational circuits evolutionary are the component of Evolvable Hardware (EHW). Evolutionary Algorithm (EA) is the core of the realization of EHW. The circuit evolutionary speed and hardware re-source consumption will be affected by the scales of initialization of chromosome codes EA. In this paper, the combinational circuit evolutionary influences of scale are analyzed in detail through examples. If the scales of initialization of chromosome codes are larger, the solution space will be very larger, and objective solutions are difficult to be searched. If the scales of initialization of chromosome codes are smaller, objective solutions may not be included in the solution space. Eventually, a novel heuristic circuit evolutionary strategy is proposed, and above difficult problem can be overcome. It has a certain guiding significance.
