“…Here q ∈ [0, 1] is an embedding parameter, such that upon setting q = 0 we have Note that an entire literature exists for the case where h = −1, in which case the method is often referred to as the homotopy perturbation method (HPM); see [17][18][19]. On the other hand, when h is picked in a specific way to minimize the error in the approximate solution formed through truncation, the method is often referred to as the optimal homotopy analysis method (OHAM); see [9][10][11][12]. We shall not go into details of the HAM solution procedure for the sake of brevity; see [1,3,4,13] for details and many worked examples.…”

“…The HAM has proven useful for a variety of such problems [4][5][6][7][8], owing to the fact that it is unique among analytical or perturbation methods in that it gives a way to minimize the error of approximations by way of an auxiliary parameter, commonly referred to as a convergence control parameter. For instance, one may minimize the error or residual error of approximate solutions over all possible choices of this parameter, and this process is referred to as the optimal HAM (or, OHAM); see [9][10][11][12]. The HAM also gives one great freedom in selecting the form of the solutions via representation of solutions [1,13], since one has control over the type of basis functions employed in such a representation.…”

“…This is essentially the essence of the so-called optimal HAM: the convergence control parameter h is optimally selected in order to minimize some measure of the error of solutions. For some examples of where this technique of minimizing error with respect to the convergence control parameter was successful, see [21,22,23,24,25,26,27].…”

“…In minimum error method the optimal values of the convergence-control parameters are obtained by the minimum of average squared residual error. The choice of the optimal values of the convergence-control parameters by using minimum error method as defined by Liao [25] is often referred to as OHAM and has been applied in the literature (see [26][27][28][29][30]). Here, the optimal values for the convergence-control parameters are obtained through the minimum of total average squared residual error.…”
