SetCross Call

sets the crossover operator

call SetCross( type<, seg><, pname, pvalue><, pname, pvalue>... );

The inputs to the SetCross subroutine are as follows:

The SetCross routine is used to assign a standard crossover operator. For multisegment encoding, the operator can be assigned to a particular solution segment with the seg parameter; otherwise a default segment of 1 is assumed. You can set different crossover operators for different segments with multiple SetCross calls. When a crossover event occurs, all segments in the parent solutions for which a crossover operator has been designated will undergo crossover. If more than one SetCross call is made for the same segment, then the last call nullifies any previous call for that segment. Also, a SetCrossRoutine call nullifies all previous SetCross calls, and a SetCross call nullifies a previous SetCrossRoutine call. Properties for the chosen crossover operator can be set with optional pname-pvalue pairs. It is also possible to set or reset operator properties with a SetProperty call.

The accepted values for type and the corresponding properties are summarized in Table 1.4. See the section "Crossover Operators" for a full description of the available operators.
