DESCRIPTION

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.
