The way to do this is to calculate the possible use another city could get
from such a tile, and include it in the calculation directly.

If a tile is in use from another city, assign a "value" to that tile.  This
"value" becomes a fourth element of the optimization function (in addition
to food/production/trade), with its own weight.  The weight can either be
set by the user or can be fixed to some very small value so that it's only
used as a tiebreaker.

The "value" a tile gets for this element could either be 0 versus 1 (not
usable by another city vs usable by another city) or X (where X is the
number of other cities who can use the tile).

This would probably be the best solution.  But can the "value" be easily
calculated?  Can you easily determine what other cities are in range of a
given tile?
