“…Finally, the tools can be grouped by a mathematical approach adopted to route finding problem, as follows: genetic algorithms (Choi et al, 2013), finite element method-based potential theory (Piehl et al, 2017), graph search-based algorithms (Nam et al, 2013;Choi et al, 2015;Guinness et al, 2014;Liu et al, 2016), conjugate direction methods (Kotovirta et al, 2009), stochastic dynamic programming , and probabilistic road map method (Takagi et al, 2014).…”
