Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

open access: yes, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Parameter-uniform numerical treatment of singularly perturbed parabolic delay differential equations with nonlocal boundary conditions [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This paper focuses on solving singularly perturbed parabolic equations of the convection-diffusion type with a large negative spatial shift and an integral boundary condition.

Timetabling in constraint logic programming [PDF]

open access: yes, 1996
In this paper we describe the timetabling problem and its solvability in a Constraint Logic Programming Language. A solution to the problem has been developed and implemented in ECLiPSe, since it deals with finite domains, it has well-defined ...

Approximation of the set of trajectories of the nonlinear control system with limited control resources

open access: yesMathematical Modelling and Analysis, 2018
In this paper the control system described by a Urysohn type integral equation is studied. It is assumed that the control functions have integral constraint.

On Solvability Conditions for the Cauchy Problem for Non-Volterra Functional Differential Equations with Pointwise and Integral Restrictions on Functional Operators

open access: yesMathematics, 2023
Cauchy problems are considered for families of, generally speaking, non-Volterra functional differential equations of the second order. For each family considered, in terms of the parameters of this family, necessary and sufficient conditions for the ...

Integrating Cardinality Constraints into Constraint Logic Programming with Sets [PDF]

open access: yesTheory and Practice of Logic Programming, 2021
AbstractFormal reasoning about finite sets and cardinality is important for many applications, including software verification, where very often one needs to reason about the size of a given data structure. The Constraint Logic Programming tool $$\{ log\} $$ provides a decision procedure for deciding the satisfiability of formulas involving very ...

A fuzzy constraint based model for bilateral multi-issue negotiations in semi-competitive environments [PDF]

open access: yes, 2003
This paper develops a fuzzy constraint based model for bilateral multi-issue negotiation in trading environments. In particular, we are concerned with the principled negotiation approach in which agents seek to strike a fair deal for both parties, but ...

On the compactness of the set of L-2 trajectories of the control system

open access: yesNonlinear Analysis, 2018
In this paper, the compactness of the set of L2 trajectories of the control system described by the Urysohn-type integral equation is studied. The control functions are chosen from the closed ball of the space L2 with radius r and centered at the origin.

An Approximation Method for Variational Inequality with Uncertain Variables

open access: yesAdvances in Mathematical Physics, 2023
In this paper, a Stieltjes integral approximation method for uncertain variational inequality problem (UVIP) is studied. Firstly, uncertain variables are introduced on the basis of variational inequality.
