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…
Grey Power Models Based on Optimization of Initial Condition and Model Parameters
Yun-Chol Jong
We propose a novel approach to improve prediction accuracy of grey power models including GM(1,1) and grey Verhulst model through optimization of the initial condition and model pa…
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…
Fast View Frustum Culling of Spatial Object by Analytical Bounding Bin
Munsu Ju, Yunchol Jong
It is a common sense to apply the VFC (view frustum culling) of spatial object to bounding cube of the object in 3D graphics. The accuracy of VFC can not be guaranteed even in cube…
Hybrid Grey Interval Relation Decision-Making in Artistic Talent Evaluation of Player
Gol Kim, Yunchol Jong, Sifeng Liu +1
This paper proposes a grey interval relation TOPSIS method for the decision making in which all of the attribute weights and attribute values are given by the interval grey numbers…
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.…
