“…Exact solutions allow researchers to design and run experiments, by creating appropriate natural conditions, to determine these parameters or functions. A variety of powerful methods, such as the sine–cosine method (Wazwaz 2004a; Bekir 2008), The first integral method (Bekir et al 2014; Jafari et al 2012), the homotopy perturbation method (Mohyud-Din and Noor 2009; Mohyud-Din et al 2011), the ( G′/G )-expansion method (Wang et al 2008; Zayed and Gepreel 2009; Guo and Zhou 2010), the Exp-function method (Bekir and Boz 2008; Akbar and Ali 2011; Naher et al 2010; Ebadi et al 2013), the modified simple equation method (Jawad et al 2010; Zayed 2011; Khan and Akbar 2013a, [b]), the exp (− Φ ( ξ ))-expansion method (Khan and Akbar 2013c), the Enhanced ( G′/G )-expansion Method (Khan and Akbar 2013d, [e]; Islam et al 2014), the tanh-function method (Wazwaz 2004b, 2005, 2007), and the modified tanh–coth function method (Lee and Sakthivel 2011) were used to find new exact traveling wave solutions of nonlinear evolution equations in mathematical physics.…”
