Practical Global Optimization Algorithm for the Sum-of-Ratios Problem
Yunchol Jong
This paper presents a practical method for finding the globally optimal solution to the sum-of-ratios problem arising in image processing, engineering and management. Unlike tradit…
A Satisfaction Degree of Optimal Value for Grey Linear Programming
Yunchol Jong
This paper considers the grey linear programming and introduces a new satisfaction degree of optimal value for the positioned linear programming of the grey problem. The λ-satisfac…
Optimization Method for Interval Portfolio Selection Based on Satisfaction Index of Interval inequality Relation
Yunchol Jong
In this paper we consider an interval portfolio selection problem with uncertain returns and introduce an inclusive concept of satisfaction index for interval inequality relation.…
An Augmented Smoothing Method of L1 -norm Minimization and Its Implementation by Neural Network Model
Yunchol Jong
In this paper we propose an augmented smoothing function for nonlinear L1 -norm minimization problem and consider a global stability of a gradient-based neural network model to min…
A Newton-Fixed Point Homotopy Algorithm For Nonlinear Complementarity Problems With Generalized Monotonicity
Yunchol Jong, Wonil Kim
In this paper has been considered probability-one global convergence of NFPH (Newton-Fixed Point Homotopy) algorithm for system of nonlinear equations and has been proposed a proba…
