Crossover multiple/single-point

Crossover Form two offspring candidate solutions (trees) from each randomly selected pair of parent trees from the parent pool. Crossover can be performed multiple ways. For example, in the single-point crossover shown in Fig. 3.59c, a location is selected randomly within the stractnre of each parent tree. Next, the respective trees are spliced at that location and offspring candidate solntions are created by mutually exchanging and combining the spliced segments of the parent trees.
