Compositional coevolution, digital circuit design, cartesian genetic programming,
switching filter design.
A divide and conquer approach is one of the methods introduced to get over the
scalability problem of the evolutionary circuit design. A complex circuit is
decomposed into modules which are evolved separately and without any interaction.
The benefits are in reducing the search space and accelerating the evaluation of
candidate circuits. In this paper, the evolution of non-interacting modules is
replaced by a coevolutionary algorithm, in which the fitness of a module depends
on fitness values of other modules, i.e. the modules are adapted to work
together. The proposed method is embedded into Cartesian genetic programming
(CGP). The coevolutionary approach was evaluated in the design of a switching
image filter which was decomposed into the filtering module and detector module.
The filters evolved using the proposed coevolutionary method show a higher
quality of filtering in comparison with filters utilizing independently evolved
modules. Furthermore, the whole design process was accelerated 1.31 times in
comparison with the standard CGP.
