Fuzzy gates interchangeability

The idea of this paper is related to possible conversions of min, max and mid fuzzy gates functions. If we want to convert basic min and max gate function to another logical function, for some reason, that can be done on several ways. For the beginning one can convert only gate inputs. In the second case only gate outputs can be inverted. The third kind of the gate interchangeability is done by the combination of inverting inputs and outputs. At the end, it is possible to design min, max and mid gates to be controllable through gate inputs information (inputs voltages).
