摘要: New implicit block formulae that compute solution of stiff initial value problems at two points simultaneously are derived and implemented in a variable step size mode. The strategy for changing the optimum performance involves halving, increasing by multiple 1.7, or maintaining current size. stability analysis methods indicates their suitability solving problems. Numerical results given compared with some existing backward differentiation formula algorithms. indicate an improvement terms accuracy.
