“…*The running time for the full search is the approximated running time using very fast simulated annealing heuristic. We assumed 300 semblance evaluations for each parameter pair, which is consistent with the results in Garabito et al (2012). window function used in the GST/QST approach smoothes the parameter estimates, which makes it harder to get good estimates in regions with rapidly changing events.…”

“…1 brute-force approach, but they are not guaranteed to find the global optimum. The most popular are simulated annealing (Müller, 2003;Garabito et al, 2012;Minato et al, 2012) and differential evolution (Barros et al, 2015).…”

“…To circumvent these problems, while keeping a reasonable computational complexity, Garabito et al (2012) proposed a global optimization strategy based on the very-fast simulated annealing (VFSA) algorithm (Sen and Stoffa, 2013) to estimate all the CRS parameters in a single search procedure. The details of the method are beyond the scope of this paper.…”

“…We use b = 0 (the correct value of the parameter) to make the visualization easier. However, plots of semblance varying the three parameters have been shown in (Garabito et al, 2012). In this figure, we also show the estimates obtained by the sequential search and the global search.…”
