Yes, you can't just delete members of the population as you suggest.
Doing that would mess with the internal structure. Other parts of the
code expect it is there. If you were to just remove the const, and call
the destroy(), it would likely crash somewhere down the line.

Notice that Brian's code doesn't _delete_ the individual, it just
re-initializes it.

You could duplicate Brian's but check for constraint violation instead
of equality, and re-init the violators.

Personally, I would start with your original suggestion of scoring
solutions outside the constraint very poorly. Try it that way first. And
if that isn't satisfactory then try Brian's. Or if the constraints are
really ugly (for example you rarely get a population that satisfies the
constraint), perhaps a variation of the interior/exterior point methods
used by Newtonian optimizations could be applied.
