算法：求解含区间参数非线性方程零解区间的EIN_Multi数值算法

1. $Z=\varnothing ;S=X_0;K=0;B=0$

2. While $S\ne \varnothing$

3. $X=Pop\left(S\right);S=S-X;$

4. if $0\in F\left(X\right)$

5. if $wid\left(X\right)<{10}^{-14}$

6. $Z=Z\cup X;$

7. else

8. computing $P_L=P_L\left(X,N_L\left(X\right)\right)$ ， $P_U=P_U\left(X,N_U\left(X\right)\right)$ and $P=P_L\bigsqcup P_U$

9. $r=\left[\min \left\{\overline{P_L},\overline{P_U}\right\},\max \left\{\underset{\_}{P_L},\underset{\_}{P_U}\right\}\right]$

10. if $0\in F^{\prime }\left(X\right)$
