No problem of expanding the value range.

Example with only two stats: food and shield. The city may provide the
following combinations (all surplus): (f=0,s=10), (f=2,s=7),
(f=11,s=2) and (f=12,s=-1). You now search the maximal sum of
sum=food_weight*food_surplus+shield_weight*shield_surplus.

food_weight shield_weight best_sum  best_combination
    1             1           13      (f=11,s=2)
    2             1           24      (f=12,s=-1)
    3             1           35      (f=11,s=2) or (f=12,s=-1)
    4             1           47      (f=12,s=-1)
   10             1           120     (f=12,s=-1)
    
    1             2           20      (f=0,s=10)
    1            10           100     (f=0,s=10)

Was this clear?
