The Linear Discrepancy of a Fuzzy Poset
In 2001, the notion of a fuzzy poset defined on a set X via a triplet (L,G, I) of functions with domain X ×X and range [0, 1] satisfying a special condition L+G+ I = 1 is introduced by J. Negger and Hee Sik Kim, where L is the ‘less than’ function, G is the ‘greater than’ function, and I is the ‘incomparable to’ function. Using this approach, we are able to define a special class of fuzzy poset...
متن کاملThe t-discrepancy of a poset
Linear discrepancy and weak discrepancy have been studied as a measure of fairness in giving integer ranks to points of a poset. In linear discrepancy, the points are totally ordered, while in weak discrepancy, ties in rank are permitted. In this paper we study the t-discrepancy of a poset, a hybrid between linear and weak discrepancy, in which at most t points can receive the same rank. Intere...
متن کاملThe Linear Extension Diameter of a Poset
The distance between two permutations of the same set X is the number of pairs of elements being in di erent order in the two permutations Given a poset P X a pair L L of linear extensions is called a diametral pair if it maximizes the distance among all pairs of linear extensions of P The maximal distance will be called the linear extension diameter of P and is denoted led P Alternatively led ...
