Diffusive Persistence on Disordered Lattices and Random Networks
Omar Malik, Melinda Varga, Alaa Moussawi +4
To better understand the temporal characteristics and the lifetime of fluctuations in stochastic processes in networks, we investigated diffusive persistence in various graphs. Glo…
Socio-economic disparities and COVID-19 in the USA
Ayan Paul, Philipp Englert, Melinda Varga
COVID-19 is not a universal killer. We study the spread of COVID-19 at the county level for the United States up until the 15 of August, 2020. We show that the prevalence of…
A high-performance analog Max-SAT solver and its application to Ramsey numbers
Botond Molnár, Melinda Varga, Zoltan Toroczkai +1
We introduce a continuous-time analog solver for MaxSAT, a quintessential class of NP-hard discrete optimization problems, where the task is to find a truth assignment for a set of…
Efficient Analog Circuits for Boolean Satisfiability
Xunzhao Yin, Behnam Sedighi, Melinda Varga +3
Efficient solutions to NP-complete problems would significantly benefit both science and industry. However, such problems are intractable on digital computers based on the von Neum…
Order-to-chaos transition in the hardness of random Boolean satisfiability problems
Róbert Sumi, Melinda Varga, Zoltán Toroczkai +1
Transient chaos is an ubiquitous phenomenon characterizing the dynamics of phase space trajectories evolving towards a steady state attractor in physical systems as diverse as flui…
Ordering in spatial evolutionary games for pairwise collective strategy updates
Gyorgy Szabo, Attila Szolnoki, Melinda Varga +1
Evolutionary games are studied with players located on a square lattice. During the evolution the randomly chosen neighboring players try to maximize their collective…
