摘要: In this paper we study the numerical solution of differential/algebraic systems F(t, y, y′) = 0. Many these can be solved conveniently and economically using a range ODE methods. Others only by small subset methods, still others present insurmountable difficulty for all current We examine first two groups problems indicate which methods believe to best them. Then explore properties third group cause fail. A reduction technique is described allows reduced ones solved. It also provides tool analytical structure systems.
