A stiff system of ordinary differential equations can be roughly characterized as that is not stiff may be much slower than using the non-stiff ( rk45 ) integrator; 

Piecewise linear approximate solution of fractional order non-stiff and stiff differential-algebraic equations by orthogonal hybrid functions July 2020 Progress in Fractional Differentiation and

Students are expected to discretize such equations, that is to construct computable Linear systems, matrix factirizations and condition, least squares, orthogonal quadratur, discretization of initial value problems, stiff and non-stiff problems,  and global error, efficiency, stability and instabilty, adaptivity, stiff and non-stiff ordinary differential equations, deterministic/stochastic models and methods. at time 0, v(0) , otherwise no unique solution. │⎩. │. ⎨. ⎧ differential equations x a b.

Stiff Equations Free Vibrations on Non-uniform and Axially Functionally Graded  temporal numerical approximations of stochastic partial differential equations. stochastic differential equation is stiff or driven by a noise with small intensity. of the Kolmogorov equation or the Ito ̄ formula and is therefore non-Markovian in  Avhandling: Strong Cosmic Censorship and Cosmic No-Hair in spacetimes with symmetries. In Paper B, we prove similar estimates in the case of stiff fluids.In Paper spacetimes satisfying the Einstein equations for a non-linear scalar field.

especially for non-stiff differential equations. The book provides a comprehensive introduction to numerical methods for solving Ordinary Differential equations

Non-Stiff Equations • Non-stiff equations are generally thought to have been “solved” • Standard methods: Runge-Kutta and Adams-Bashforth-Moulton • ABM is implicit!!!!! • Tradeoff: ABM minimizes function calls while RK maximizes steps. • In the end, Runge-Kutta seems to have “won”

The methods tested include extrapolation methods, variable-order Adams methods, Runge-Kutta methods based on the formulas of Fehlberg, and appropriate methods from the SSP and IMSL subroutine libraries. (In some cases the Non-Stiff Equations • Non-stiff equations are generally thought to have been “solved” • Standard methods: Runge-Kutta and Adams-Bashforth-Moulton • ABM is implicit!!!!! • Tradeoff: ABM minimizes function calls while RK maximizes steps. • In the end, Runge-Kutta seems to have “won” 2020-05-12 AutoTsit5(Rosenbrock23()) handles both stiff and non-stiff equations. This is a good algorithm to use if you know nothing about the equation.
