Webb22 dec. 2024 · First, Shannon came up with a formula for the minimum number of bits per second to represent the information, a number he called its entropy rate, H. This number quantifies the uncertainty involved in determining which message the source will generate. Webbwhich the application of sharp restart decreases or increases the completion-time’s entropy. Our work sheds ﬁrst light on the intricate interplay between restart and randomness – as gauged by the Boltzmann-Gibbs-Shannon entropy. Keywords: Stochastic resetting; Sharp restart; Boltzmann-Gibbs-Shannon entropy; Kullback-Leibler divergence.
