Evolvable hardware design of combinational logic circuits

Evolvable Hardware (EHW), as an alternative method for logic design, became more attractive recently, because of its algebra-independent techniques for generating selfadaptive self-reconfigurable hardware. This thesis investigates and relates both evaluation and evolutionary processes, emphasizing the need to address problems arising from data complexity. Evaluation processes, capable of evolving cost-optimised fully functional circuits are investigated. The need for an extrinsic EHW approach (software models) independent of the concerns of any implementation technologies is emphasized. It is also shown how the function description may be adapted for use in the EHW approach. A number of issues of evaluation…
