large-deviations

Code developed for a research project at the University of Cambridge, supervised by Robert Jack.

Here, we propose an adaptive random walk (ARW), which, differently from the maximum entropy random walk, maximizes dispersion by updating its transition rule on the local information collected while exploring the network. The ARW is obtained via a large-deviation representation of the MERW as a finite-time rare event of an unbiased random walk a…

We derive asymptotic behavior of the probability of high-level excursion for the maximal increment of a Gaussian random walk.

We derive asymptotic behavior of the probability of high-level excursion for the maximal increment of the Wiener process.

This project is an implementation of the Adaptive Power Method (APM). It simulates a random walk on an Erdős-Rényi random graph to compute the scaled culumant generating function (SCGF) and rate function of the mean degree a time additive observable.

This code comes from my master thesis. It takes a nonlinear system of Stochastic Differential Equations (in this case a Lotka-Volterra system) and finds the `most typical way' in which a very rare events happens, due to stochastic fluctuations.
