In this paper, a triply cubic polynomials approach is proposed firstly
for solving the globally convergent algorithm of coefficient inverse problems in three
dimension. Using Taylor type expansion for three arguments to construct tripled cubic
polynomials for the approximate solution as identifying coefficient function of parabolic
initial-boundary problems, in which unknown coefficients appeared at nonlinear term.
The presented computational approach is effective to execute in spatial 3D issues
arising in real world. Further, the complete algorithm can be straightforwardly
performed to lower or higher dimensions case
