Bipolar Fuzzy Minimum-Weight Satisfiability under Continuous t-Norms: A Clause-Witness Branch-and-Bound Framework
Amin Ghodousian, Mohammad Sedigh Chopannavaz
Minimum-weight satisfiability asks for a satisfying Boolean assignment of minimum cost, while many fuzzy decision and knowledge systems operate with graded positive and negative re…
A bipolar fuzzy relation equation framework for clinical decision support systems
Amin Ghodousian, Mohammad Sedigh Chopannavaz
Clinical decision support frequently involves heterogeneous measurements, expert assessments, and guideline-based knowledge whose relationships to clinical decisions are gradual ra…
On the resolution and linear optimization problems subject to a system of bipolar fuzzy relational equalities defined with continuous Archimedean t-norms
Amin Ghodousian, Mohammad Sedigh Chopannavaz, Witold Pedrycz
This paper considers the linear objective function optimization with respect to a more general class of bipolar fuzzy relational equations, where the fuzzy compositions are defined…
On the nonlinear programming problems subject to a system of generalized bipolar fuzzy relational equalities defined with continuous t-norms
Amin Ghodousian, Mohammad Sedigh Chopannavaz
As a starting point, this paper develops the system of bipolar fuzzy relational equations (FRE) to the most general case, where bipolar FREs are defined by an arbitrary continuous…
