I have two patches to make the geqo initialization and mutation
slightly better.

The first adjusts the mutation swaps to avoid having to re-pick
ties.  The second changes the initialization and shuffling algorithm
for the gene array to use an in-place Fisher-Yates shuffling
algorithm.

Diffs against commit 49124613f134b04594b1a5c46368eb0a5db16d4b
(i.e. tip of master as of when I re-made the diff).

On my system the patches pass a ./configure; make; make check
