An Improved Block Backward Differentiation Formula for Stiff Differential Equations

Description

 In this work, we derived eight-order, implicit block formula using backward differentiation  method with two off-step points for solving stiff ordinary differential equations. We solve some  standard set of stiff initial value problems (IVPs) using the new method. We then compared  the numerical results with the existing methods which have solved the same set of ivps. We
 have also verified the consistency, order and stability of the method whereby, method is found to be A- stable and consistent.
