The GA Procedure

The ReadParent call reads selected solution elements into an array in a user crossover subroutine. The inputs to the ReadParent subroutine are as follows:

selected	is a parameter passed to the user subroutine by the GA procedure, which points to the selected solution family.
seg	is the segment of the desired parent solution to be obtained.
n	is the number of the parent, starting at 1.
destination	is an array in which to store the solution elements.

The ReadParent subroutine is called inside a user crossover operator subroutine to obtain the elements of selected parent solutions. Normally you would then manipulate and combine the elements of the two parents and use a WriteChild call to create the child offspring and complete the action of the crossover operator.
