“…which is the exact solution by one step .The other methods, LTNHPM [15], and VIMHP [16], take more than one step to reached the exact or approximation solution. This problem is solved in [15], by LTNHPM, the six term approximate solution takes the form: From comparison, it is clear that the rate of convergence of NIM is faster than, LTNHPM, VIMHP.…”
