Problem with seeding

Problem with my seeding approach: All the good solutions are clustered in local optima.
The feature-rich seed has 5704 selected features. Subsequent good solutions are only slightly different.

What to do:
·         Make a cluster of good solutions, with a variety of “richness”…
·         OR, better yet: let the user introduce reference points. Instead of seeking to minimize the objective, minimize the difference (desired point – actual point)
o   Desired number of features
o   Desired number of defects
o   Desired number of used before
o   Desired cost
