....long. algorithm [8] by Chang and Hwang takes a di#erent approach and minimizes the number of expensive user defined predicates being evaluated. It requires the preference function to be monotonic and assumes that a ceiling value of the function can be easily derived. Sideway Value Algebra (SVA) [19], on the other hand, focuses on the algebraic representation of those preference scores without worrying about how they are generated. It keeps the preference scores as sideway values and propagate them during the evaluation of the algebraic operators. Our study distinguishes itself from those ....
