It states in the abstract that it can be used solely when the root is zero. Thus, the title f(0) = 0 is correct, the algorithm only converges to a root (yeah, with order 3 and only one function evaluation per iteration) if such root is zero. The equation Namir used was (7) in the Thukral's 2016 paper. Such equation only converges to zero roots (as stated in the abstract and conclusions). In the same paper there's a reference to another "Thukral method" (equations (19)(20)) which is the one in the 2008 paper by the same author. Equation (20) has an error (in the 2016 paper), but it is not related to equation (7), which is new. Regards. César  Information must flow.
