%0 Journal Article %A Madrid Labrador, Nicolás Miguel %A Ojeda Aciego, Manuel %T The f-index of inclusion as optimal adjoint pair for fuzzy modus ponens %D 2023 %@ 0165-0114 %U http://hdl.handle.net/10498/38482 %X We continue studying the properties of the f-index of inclusion and show that, given a fixed pair of fuzzy sets, their f-index of inclusion can be linked to a fuzzy conjunction which is part of an adjoint pair. We also show that, when this pair is used as the underlying structure to provide a fuzzy interpretation of the modus ponens inference rule, it provides the maximum possible truth-value in the conclusion among all those values obtained by fuzzy modus ponens using any other possible adjoint pair. %K Fuzzy logic %K f-index of inclusion %K Fuzzy inclusion %K Inclusion measures %K Residuated lattice %K Galois connection %~ Universidad de Cádiz
