In matematica, un'equazione rigida (in inglese stiff: rigido, duro, difficile) è un'equazione differenziale per la quale certi metodi di soluzione sono numericamente instabili a meno che il passo d'integrazione sia preso estremamente piccolo.

The Canadian Journal of Chemical Engineering 90 :4, 804-823. Stiff and differential-algebraic problems arise everywhere in scientific computations (e.g., in physics, chemistry, biology, control engineering, electrical network analysis, mechanical systems). Many applications as well as computer programs are presented. (source: Nielsen Book Data) 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 towards general purpose procedures for the solution of stiff differential equations. There are effective codes available based on these procedures, but it is necessary that the user have some idea how they work in order to take full advantage of them. Lastly we discuss what are realistic goals when solving a stiff differential equation.

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”

I like Shampine's working definition the best: a differential equation is stiff if explicit methods are less computationally efficient than implicit methods. I have to solve a stiff non-linear differential equation. I tried ode45,ode15s and ode23s amongst MATLAB solvers, none of them has worked.

The effects of stiffness are investigated for production codes for solving non-stiff ordinary differential equations. First, a practical view of stiffness as related to methods for non-stiff problems is described. Second, the interaction of local error estimators, automatic step size adjustment, and stiffness is studied and shown normally to equation is the highest derivative in the equation.
