abstract = "Production genetic algorithms is proposed to enable
grammar structure as well as hardware description
language (HDL) programs to evolve, toward an automated
hardware design system through an evolutionary process.
Evolutionary computation and methods make it possible
to design hardware that works in unknown and
non-stationary environments without explicit design
knowledge. In the proposed system, hardware
specifications, which produce circuit behaviours, are
automatically generated as HDL programs according to
the grammar defined as in a rewriting system and then
evolve through production genetic algorithms (PGAs),
also proposed here. The PGAs introduce new chromosome
representation and genetic operators to create
self-genesis mechanisms in hardware design similar to
living systems. An experimental result shows that
through an evolutionary process based on the PGAs, a
hardware specification program expands its circuit
scale and as a result increases its functionality",
