Learning to Synchronize in Minimum Time
Kevin. P. O'Keeffe
The minimum-time feedback law for driving a population of coupled oscillators into synchrony is unknown. Here we settle it for identical Kuramoto oscillators under an instantaneous…
Synchrony by Birth and Death
K. P. O'Keeffe
A population of oscillators typically synchronizes because coupling pulls their phases together. Here we consider malthusian oscillators whose coupling is demographic: oscillators…
A solvable normal form for coupled swarmalators
Kevin P. O'Keeffe
Swarmalators are mobile generalizations of phase oscillators. Introduced to model systems in which sync and self-assembly interact, they remain poorly understood theoretically. Unl…
Unsteady phase waves in the 1D swarmalator model with inertia
Kevin P. O'Keeffe
We study a one-dimensional swarmalator model with inertia. Previous studies have focused almost exclusively on the overdamped limit. We find inertia introduces a new unsteady colle…
Curiosity-driven RL for symbolic equation solving
Kevin P. O'Keeffe
We explore if RL can be useful for symbolic mathematics. Previous work showed contrastive learning can solve linear equations in one variable. We show model-free PPO \cite{schulman…
