In this paper , we have presented Homotopy Perturbation Method
(HPM) to solve nonlinear parabolic equation with nonlocal boundary
conditions. This method provides an analytical solution by utilizing
only the initial condition. The HPM allows for the solution of the
nonlinear parabolic equations to be calculated in the form of a series
with easily computable components. The obtained results are presented
and only four terms are required to obtain an approximate solution that
is accurate and efficient.
