PGASetUserFunction(8) PGAPack PGASetUserFunction(8)NAME
PGASetUserFunction - specifies the name of a user-written function call to provide a specific GA capability (e.g., crossover, mutation,
This function MUST be used when using a non-native datatype and must be called once for each of:
PGA_USERFUNCTION_CREATESTRING -- String creation
PGA_USERFUNCTION_MUTATION -- Mutation
PGA_USERFUNCTION_CROSSOVER -- Crossover
PGA_USERFUNCTION_PRINTSTRING -- String Output
PGA_USERFUNCTION_COPYSTRING -- Duplication
PGA_USERFUNCTION_DUPLICATE -- Duplicate Checking
PGA_USERFUNCTION_INITSTRING -- Initialization
PGA_USERFUNCTION_BUILDDATATYPE -- MPI Datatype creation
PGA_USERFUNCTION_STOPCOND -- Stopping conditions
PGA_USERFUNCTION_ENDOFGEN -- Auxiliary functions at the end of each generation
It MAY be called when using a native datatype to replace the built-in functions PGAPack has for that datatype (For example, if the Integer
data type is used for a traveling salesperson problem, the user may want to provide their own custom crossover operator). See the user
guide and the examples in the examples directory for more details.
ctx - context variable
- symbolic constant of the user function to set
f - name of the function to use
void PGASetUserFunction(ctx, constant, f)
void MyStringInit(PGAContext *, void *);
PGASetUserFunction(ctx, PGA_USERFUNCTION_INITSTRING, MyStringInit);
