Evolution of Digital Logic Functionality via a Genetic Algorithm

Abstract: Digital logic forms the functional basics of most modern electronic equipment and as such the creation of novel digital logic circuits is an active area of computer engineering research. This study demonstrates that genetic algorithms can be used to evolve functionally useful sets of logic gate interconnections to create useful digital logic circuits. The efficacy of this approach is illustrated via the evolution of AND, OR, XOR, NOR, and XNOR functionality from sets of NAND gates, thereby illustrating that evolutionary methods have the potential be applied to the design of digital electronics.
