摘要
构造了一类Adams型的并行多步混合方法 ,得到了A 稳定的三步三阶方法和A(α) 稳定的四步四阶 (α =89.99°)及五步五阶 (α =84.92°)方法的具体计算公式 .数值试验表明 。
A class of Adams type pararell hybrid multistep algorithms is constructed.A stable formula of 3 step 3rd order,A(α) stable formula of 4 step 4th order with α=89.99° and A(α) stable formula of 5 step 5th order with α=84.92° are obtained.The numerical example shows that these methods are efficient for solving stiff ordinary equations.
