“…Method has the efficiency index equal to 1.5651, which is better to Newton's method with efficiency index equal to 1.414 and the classical third order methods (1.442), such as Weerakoon and Fernando method, Chebyshev's method, Halley's method and Super-Halley method, fifth order method (1.495) of Kou, Li, Wang [24]. When compared with the sixth order methods of Parhi, Gupta, [20] and Kou and Li [13], proposed method behaves either similarly or better on the examples considered.…”
