In conventional SISO fuzzy expert systems -element input -element output, the implication step requires the operations using compositional rule-based inference CRI and individual rule-based inference IRI. However, this introduces excessive complexity. This paper proposes two methods, sort compositional rule-based inference SCRI and sort individual rule-based inference SIRI aiming at reducing both temporal and spatial complexity by changing the operation of the implication step to log2. We also propose a divide-and-conquer technique, called Quicksort, to verify the accuracy of SCRI and SIRI algorithms deployment to easily outperform the CRI and IRI methods.
