“…Due to this advantage, the even swaps method has attracted much attention, and its theoretical developments were mainly in three directions including the software development (Mustajoki & Hämäläinen, 2005, 2007, the combination with other methods (Dereli & Altun, 2012;Elahi & Yu, 2012;Li & Ma, 2008), and the consideration of biases (Lahtinen & Hämäläinen, 2016;Lahtinen et al, 2020). Meanwhile, the even swaps method have been applied to many realms (Gomes et al, 2012;Kajanus et al, 2001;Milutinovic et al, 2018). The studies of the even swaps method on the software development and the combination with other methods extended the scope of applications of the even swaps method.…”
