The Emergence of League and Sub-League Structure in the Population Lotto Game
Giovanni Artiglio, Aiden Youkhana, Joel Nishimura
In order to understand if and how strategic resource allocation can constrain the structure of pair-wise competition outcomes in competitive human competitions we introduce a new m…
Implication Avoiding Dynamics for Externally Observed Networks
Joel Nishimura, Oscar Goodloe
Previous network models have imagined that connections change to promote structural balance, or to reflect hierarchies. We propose a model where agents adjust their connections to…
When a `rat race' implies an intergenerational wealth trap
Joel Nishimura
Two critical questions about intergenerational outcomes are: one, whether significant barriers or traps exist between different social or economic strata; and two, the extent to wh…
Critically Slow Learning in Flashcard Learning Models
Joel Nishimura
Algorithmic education theory examines, among other things, the trade-off between reviewing old material and studying new material: time spent learning the new comes at the expense…
Swap connectivity for two graph spaces between simple and pseudo graphs and disconnectivity for triangle constraints
Joel Nishimura
With sufficient time, double edge-swap Markov chain Monte Carlo (MCMC) methods are able to sample uniformly at random from many different and important graph spaces. For instance,…
The connectivity of graphs of graphs with self-loops and a given degree sequence
Joel Nishimura
`Double edge swaps' transform one graph into another while preserving the graph's degree sequence, and have thus been used in a number of popular Markov chain Monte Carlo (MCMC) sa…
Configuring Random Graph Models with Fixed Degree Sequences
Bailey K. Fosdick, Daniel B. Larremore, Joel Nishimura +1
Random graph null models have found widespread application in diverse research communities analyzing network datasets, including social, information, and economic networks, as well…
Frequency adjustment and synchrony in networks of delayed pulse coupled oscillators
Joel Nishimura
We introduce a system of pulse coupled oscillators that can change both their phases and frequencies; and prove that when there is a separation of time scales between phase and fre…
Probabilistic Convergence Guarantees for Type II Pulse Coupled Oscillators
Joel Nishimura, Eric J. Friedman
We show that a large class of pulse coupled oscillators converge with high probability from random initial conditions on a large class of graphs with time delays. Our analysis comb…
Robust convergence in pulse coupled oscillators with delays
Joel Nishimura, Eric J. Friedman
We show that for pulse coupled oscillators a class of phase response curves with both excitation and inhibition exhibit robust convergence to synchrony on arbitrary aperiodic conne…
Explosive Percolation in Social and Physical Networks
Eric J. Friedman, Joel Nishimura
We discuss several interesting random network models which exhibit (provable) explosive transitions and their applications.
