Pick the nearest berry bush the gatherer can still bring home from

A gatherer with a limited amount of strength should only head for food it can reach and still walk back from. The way home costs something different from the way out, and doubling the trip is wrong. Here is the calculation.

Why this works

A trip out and back is not twice the way out, because the cost depends on which cells you step onto, and that changes with direction. Adding the real cost of each leg tells you whether the gatherer can still get home.

When not to use it

Skip it when the gatherer can camp out, find food on the way or be carried home, since the limit on the return then does not apply. It also adds little on flat, evenly priced ground, where doubling the one-way trip is close enough.
