Optimal class scheduling with minimum distributed vacant seats using binary linear programming
Ohmchana Klinsod, Parin Chaipunya
In this paper, we propose a mathematical model for class scheduling using binary linear programming with the aims to automate the tedious task and to minimize the leftover seats di…
The proximal point method and its two variants for monotone vector fields in Hadamard spaces
Parin Chaipunya, Fumiaki Kohsaka
We prove existence and convergence of sequences generated by the proximal point method and its two variants for monotone vector fields in Hadamard spaces. Before obtaining our resu…
A Stackelberg Game of Demand Response from the Aggregator's Perspective
Seangleng Khe, Parin Chaipunya, Athikom Bangviwat
In this paper, we investigate on the modeling of demand response activities between the single aggregator and multiple participating consumers. The model incorporates the bilevel s…
A self-adaptive subgradient extragradient method with conjugate gradient-type direction for pseudomonotone variational inequalities
Ibrahim Arzuka, Parin Chaipunya, Poom Kumam
This paper introduces a subgradient extragradient algorithm with a conjugate gradient-type direction to solve pseudomonotone variational inequality problems in Hilbert spaces. The…
A product of strongly quasi-nonexpansive mappings in Hadamard spaces
Wiparat Worapitpong, Parin Chaipunya, Poom Kumam +1
In this paper, we prove that the product of strongly quasi-nonexpansive -demiclosed mappings is also a strongly quasi-nonexpansive orbital -demiclosed mapping in Hadamard s…
Variational principles using a non-symmetric non-triangular distance
Natthaya Boonyam, Parin Chaipunya, Poom Kumam
We consider Borwein-Preiss and Ekeland variational principles using distance functions that neither is symmetric nor enjoy the triangular inequality. All the given results rely exc…
