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. Webb6 sep. 2024 · Shannon entropy Probabilities are, by definition, in the range between 0 and 1 and, therefore, non-negative. The logarithm of a probability is non-positive. Multiplying the logarithm of a probability with a probability doesn’t change the sign. The sum of non-positive products is non-positive.
