The backward differentiation formula (BDF) is a family of implicit methods for the numerical integration of ordinary differential equations. They are linear multistep methods that, for a given function and time, approximate the derivative of that function using information from already computed time points, thereby increasing the accuracy of ...
Another type of multistep method arises by using a polynomial to approximate the solution of the initial value problem rather than its derivative , as in the Adams methods. We them differentiate and set equal to to obtain an implicit formula for . These are called backward differentiation formulas.
Backward Differentiation Methods These are numerical integration methods based on Backward Differentiation Formulas (BDFs). They are particularly useful for stiff differential equations and Differential-Algebraic Equations (DAEs).

Finite difference schemes, using Backward Differentiation Formula (BDF), are studied for the approximation of one-dimensional diffusion equations with an obstacle term, of the form
Backward differentiation formulas (BDF), a class of implicit methods, have been successfully used for resolving stiff IVPs. Classical BDF methods are derived using polynomial basis functions. In this paper, we develop radial basis function based finite difference (RBF-FD) type BDF methods for solving stiff problems.
The Backward Differentiation Formula (BDF) solver is an implicit solver that uses backward differentiation formulas with order of accuracy varying from one (also know as the backward Euler method) to five. BDF methods have been used for a long time and they are known for their stability.
