The comparator circuit evaluation problem can be solved in polynomial time, and so "'CC "'is contained in "'NC "'are incomparable, and so both containments are strict.

:I don't know if this is incredibly stupid or not, but given that you seem to have 4 segments with 3 different slopes you may use some comparator circuit to decide when to switch from a " slope " to another.

A "'window detector circuit "', also called "'window comparator circuit "'or "'dual edge limit detector circuits "'is used to determine whether an unknown input is between two precise reference threshold voltages.
