Currently there are two general ways to solve stiff differential equations numerically. The first approach is based on implicit methods and the second uses explicit stabilized Runge–Kutta methods, also known as Chebyshev methods. Implicit methods are great for very stiff problems of not very large dimension, while stabilized explicit methods are efficient for very big systems of not very large ...

Resumen: Este art́ıculo presenta un nuevo método de integración numérica de ecuaciones diferenciales ordinarias basado en la cuantificación de las variables de estado. Utilizando conceptos de integración impĺıcita, el nuevo método denominado BQSS (Backward Quantized State Systems) permite integrar sistemas stiff de manera eficiente. Siendo el primer método de cuantificación para sistemas stiff, ...
