abstract = "Evolvable hardware (EHW) is facing the problems of
scalability. Evolutionary algorithms often trap into
local optima, or stalling in the later procedure. This
paper analyses the difficulty of EHW. To improve the
efficiency of Cartesian Genetic Programming (CGP),
Neighbourhood searching and orthogonal experiment
design are tailed to an orthogonal mutation operator
and a new Orthogonal Cartesian Genetic Programming
algorithm is proposed. Demonstrated by experiments on
the benchmark, the proposed Orthogonal Cartesian
Genetic Programming can jump out of Local optima and
decrease the stalling effect.",
