“…Traditionally, three computationally expensive steps are involved in ABM calibration; running the model, measuring calibration quality and locating parameters of interest. As remarked 1 In the last two decades a variety of ABM have been applied to study many different issues across a broad spectrum of disciplines beyond economics and including ecology (Grimm and Railsback, 2013), health care (Effken et al, 2012), sociology (Macy and Willer, 2002), geography (Brown et al, 2005), bio-terrorism (Carley et al, 2006), medical research (An and Wilensky, 2009), military tactics (Ilachinski, 1997) and many others. See also Squazzoni (2010) for a discussion on the impact of ABM in social sciences, and Roventini (2012, 2017) for an assessment of macroeconomic policies in agent-based models.…”
