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…
A two-phase-ACO algorithm for solving nonlinear optimization problems subjected to fuzzy relational equations
Amin Ghodousian, Sara Zal
In this paper, we investigate nonlinear optimization problems whose constraints are defined as fuzzy relational equations (FRE) with max-min composition. Since the feasible solutio…
