The modified WE program with fluctuating bins N (randomly uniformly chosen from 50≤N≤100) is applied to study the duration of transition events for a Brownian particle in double well potentialU(x)=5.0kBT[1−x2]2. Panel (a) shows the time series of the number of bins N; only the first 100 values of N are included. Panel (b) shows that the modified WE program with fluctuating bins reproduces the results from static bins.
