Almost generalized uniform matroids and excluded minors

Hyungju Park

We establish that matroids characterized by the Tutte polynomial with coefficients vanishing for precisely coincide with $…

Reinforcement learning with distance-based incentive/penalty (DIP) updates for highly constrained industrial control systems

Hyungjun Park, Daiki Min, Jong-hyun Ryu +1

Typical reinforcement learning (RL) methods show limited applicability for real-world industrial control problems because industrial systems involve various constraints and simulta…

Delayed Q-update: A novel credit assignment technique for deriving an optimal operation policy for the Grid-Connected Microgrid

Hyungjun Park, Daiki Min, Jong-hyun Ryu +1

A microgrid is an innovative system that integrates distributed energy resources to supply electricity demand within electrical boundaries. This study proposes an approach for deri…

Grothendieck-Plücker images of Hilbert schemes are degenerate

Donghoon Hyeon, Hyungju Park

We study the decompositions of Hilbert schemes induced by the Schubert cell decomposition of the Grassmannian variety and show that Hilbert schemes admit a stratification into loca…

Algorithms for Determining Birationality of Parametrization of Affine Curves

Hyungju Park

Let be an arbitrary field, and C be a curve in A^n defined parametrically by x_1=f_1(t),...,x_n=f_n(t), where f_1,...,f_n\in k[t]. A necessary and sufficient condition for the…

Homogeneous Cyclotomic Polynomials and Rationality of Curves

Hyungju Park

This paper is withdrawn. The current main theorem can be proved by using a simple field theory. The main theorem is to placed by another theorem, shortly.

An Algorithmic Proof of Suslin's Stability Theorem over Polynomial Rings

H. Park, C. Woodburn

Let be a field. Then Gaussian elimination over and the Euclidean division algorithm for the univariate polynomial ring allow us to write any matrix in or $…
