sets the mutation operator

The inputs to the SetMut subroutine are as follows:

The SetMut routine is used to assign a standard mutation 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 mutation operators for different segments with multiple SetMut calls. When a mutation event occurs, all the operators will applied to the same solution. If more than one SetMut call is made for the same segment, then the last call nullifies any previous call for that segment. Also, a SetMutRoutine call nullifies all previous SetMut calls, and a SetMut call nullifies a previous SetMutRoutine call. Properties for the chosen mutation 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 3.5. See the section Mutation Operators for a full description of the available operators.
