By the method of lines (MOL) and semi-discretization approximation, we transform the PDEs into a linear system of first-order differential equations whose result fulfills a recurrence relation including the exponential function of a matrix. The techniques used are L0-stable, factual (reliable), and do not compel the application of complicated computation. The refined parallel algorithm is also applied to a problem and is seen to be highly factual, with less error than the methods already existing.enFifth order parallel splitting techniques for two dimensional heat equation with nonlocal boundary conditionThesis
