Improved bounds for the double cap conjecture
Domonkos Czifra, Ákos Dúcz, Máté Matolcsi +2
In 1974, Witsenhausen asked for the maximum possible density of a measurable subset of the unit sphere such that contains no pa…
A nonexistence criterion and new constructions for Butson Hadamard matrices
Domonkos Czifra, Máté Matolcsi, Ferenc Szöllősi
Based on the concept of positive definite functions on finite groups, we present a new necessary condition for the existence of Butson Hadamard matrices . We use this cond…
Dynamic Memory Based Adaptive Optimization
Balázs Szegedy, Domonkos Czifra, Péter Kőrösi-Szabó
Define an optimizer as having memory if it stores dynamically changing vectors in the parameter space. Classical SGD has memory , momentum SGD optimizer has and Adam…
Towards solving the 7-in-a-row game
Domonkos Czifra, Endre Csóka, Zsolt Zombori +1
Our paper explores the game theoretic value of the 7-in-a-row game. We reduce the problem to solving a finite board game, which we target using Proof Number Search. We present a nu…
Switchover phenomenon induced by epidemic seeding on geometric networks
Gergely Ódor, Domonkos Czifra, Júlia Komjáthy +2
It is a fundamental question in disease modelling how the initial seeding of an epidemic, spreading over a network, determines its final outcome. Research in this topic has primari…
