摘要
区间牛顿法具有较强的全局收敛性。在实际应用过程中,只要给出非线性方程组中所有自变量的变化范围,区间牛顿法就能在数学上保证找到非线性方程组的所有解。因此,广泛应用于化工过程计算与优化中。
A global convergence algorithm called interval Newton algorithm is introduced in this paper.It provides the power to find out all solutions of nonlinear equations,which only the upper and lower bounds are available for all variables.So it is used extensively in the calculation of chemical engineering simulation.
