The s-step Adams–Bashforth method has order s, while the s-step Adams–Moulton method has order + (Hairer, Nørsett & Wanner 1993, §III.2). These conditions are often formulated using the characteristic polynomials ρ ( z ) = z s + ∑ k = 0 s − 1 a k z k and σ ( z ) = ∑ k = 0 s b k z k . {\displaystyle \rho (z)=z^{s}+\sum _{k=0}^{s-1 ...
1768 - Leonhard Euler publishes his method. 1824 - Augustin Louis Cauchy proves convergence of the Euler method. In this proof, Cauchy uses the implicit Euler method. 1855 - First mention of the multistep methods of John Couch Adams in a letter written by Francis Bashforth. 1895 - Carl Runge publishes the first Runge–Kutta method.
The Adams–Bashforth method (a numerical integration method) is named after John Couch Adams (who was the 1847 Senior Wrangler to Bashforth's Second Wrangler) and Bashforth. They used the method to study drop formation in 1883. [4]
A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method). Consider the differential equation ′ = (,), =, and denote the step size by .
The pink region is the stability region for the second-order Adams–Bashforth method. Let us determine the region of absolute stability for the two-step Adams–Bashforth method y n + 1 = y n + h ( 3 2 f ( t n , y n ) − 1 2 f ( t n − 1 , y n − 1 ) ) . {\displaystyle y_{n+1}=y_{n}+h\left({\tfrac {3}{2}}f(t_{n},y_{n})-{\tfrac {1}{2}}f(t_{n ...

Adams method may refer to: A method for the numerical solution of ordinary differential equations, also known as the linear multistep method;
The simplest method from this class is the order 2 implicit midpoint method. Kraaijevanger and Spijker's two-stage Diagonally Implicit Runge–Kutta method:
