A backward pawn is just one type of weak pawn. A weak pawn is a pawn that cannot
be defended by other pawns, and thus requires pieces to guard it. Those pieces
in turn become less active and more restricted.

I think it's a better idea to avoid thinking of "backward pawns" or "isolated
pawns" or "doubled pawns", but rather to focus on the weakness of the pawn
structure more generally (if you're wanting a "perfect" method). For example, it
would probably be better to have a function that detected whether or not a pawn
was weak (unable to be defended by fellow pawns), rather than detect doubled
pawns and tack on a penalty, because doubled pawns, just like isolated and
backward pawns, are not always weak.

I suppose since it is possible for an isolated pawn to not be weak, that a
better "weak" pawn definition is "a pawn that requires the support of pieces."
As with most things in chess, detecting this statically is not going to be
perfect.
