A new variable topology genetic coding for evolutionary hardware

Recently, the approaches that were all developed with random circuit matrix as evolutionary framework have been widely used for evolutionary hardware and evolutionary hardware design. In this paper, a novel variable topology genetic coding including a new logic circuit representation and corresponding evolutionary algorithm for evolutionary hardware design is proposed. In comparison with random circuit matrix based studies, the proposed approach is able to reduce searching space for evolutionary computation, obtain better flexibility for logic circuit encoding, and increase exploration possibility for more complex evolutionary hardware. Simulation results demonstrate the validity and performance of the proposed method.
