2 <strong>Genetic</strong> <strong>Algorithms</strong> <strong>with</strong> <strong>Simulated</strong> <strong>Binary</strong> <strong>Crossover</strong> (SBX)<br />
There exists a number of real-parameter GA implementations, where crossover and mutation operators<br />
are applied directly on real parameter values. One of the early implementations was by Wright (1990),<br />
where a linear crossover operator created three solutions(x(1;t) i+x(2;t) i),(1:5x(1;t) i?0:5x(2;t) i), and<br />
i)from two parent solutionsx(1;t) iandx(2;t) iat generationtand choose the best<br />
two solutions as children solutions. Goldberg introduced the concept of virtual alphabets in the context of<br />
real-coded GAs (Goldberg, 1991). Eshelman and Schaffer (1993) have introduced the notion of interval<br />
schemata for real-coded genetic algorithms and suggested a blend crossover (BLX- ) operator. For two<br />
parent solutionsx(1;t) i?(x(2;t) iandx(2;t) i?x(1;t) i),x(2;t) i(assumingx(1;t) i+(x(2;t) i?x(1;t) i
