As the output range starts with zero, do nothing for that. Scale the new input range so it fits the output range, this is easy as they now both starts at zero: multiply the value by 255/2 0..2 * 2/255 -> 0..255. Done!

Nettet10. apr. 2024 · It has nothing to do even with linear programming. It's a simple mathematical fact: $$\min \left( f \left( x \right) \right) = - \max \left( -f \left( x \right) \right)$$ which still holds when you restrict the domain of the function by the constraints (actually to a convex polyhedron in case of LP).
