Web26 Feb 2024 · We study the rare fluctuations or large deviations of time-integrated functionals or observables of an unbiased random walk evolving on Erd\"os-R\'enyi random graphs, and construct a modified, biased random walk that explains how these fluctuations arise in the long-time limit. Two observables are considered: the sum of the degrees … Web1. unbiassed - characterized by a lack of partiality; "a properly indifferent jury"; "an unbiasgoted account of her family problems". unbiased, indifferent. impartial - showing lack of favoritism; "the cold neutrality of an impartial judge". 2.

Additional conditions can be then applied to this base … Web25 Apr 2024 · We propose local-biased random walks on general networks where a Markovian walker is defined by different types of biases in each node to establish transitions to its neighbors depending on their degrees. For this ergodic dynamics, we explore the capacity of the random walker to visit all the nodes characterized by a global mean first …
