Numerical experiment} \vskip0.2cm In this section, we give an example to illustrate the algorithms in this paper. We perform the algorithms by Matlab R2008a running on a PC Desktop with Core(TM) i3CPU M550 3.20GHz with 4GB Ram. \vskip0.2cm \noindent {\bf Example 4.1} Let $H=\mathbb{R}^3$ and $U_1=\{(x_1,x_2,x_3): x_1\in[0,1], x_2\geq 0,x_3\geq 0\}$, $U_2=\{(x_1,x_2,x_3): x_1\geq 0,x_2\in[0,2], x_3\geq 0\}$ and $U_3=\{(x_1,x_2,x_3): x_1\geq 0,x_2\geq 0, x_3\in[0,3]\}$. For each $i=1,2,3$, let $f_i(x,y)=(y_i-x_i)\|x\|$ for all $x=(x_1,x_2,x_3), y=(y_1,y_2,y_3)\in U_i$. From \cite{Wang2018} it follows that each $f_i$ satisfies the conditions (i)-(iv) with the Lipschitz constants $c_1=c_2=1$. Let $V_j=\{(x_1,x_2,x_3): x_1\in\mathbb{R}, 0\leq x_2\leq j,x_3\geq 0\}$ for each $j=1,\ldots,M$. Define the nonexpansive mapping $S_j$ on $V_j$ by $S_jx=(-\frac{x_1}{2}, \frac{x_2^2}{6j},\frac{x_3}{2})$ for $j=1,\ldots,M$. Obviously, $\mathcal{F}=\cap_{i=1}^3 EP(f_i)\cap(\cap_{j=1}^M)Fix(S_j)=\{(0,0,0)\}$. In Algorithm 3.1 and 3.2, put the sequence $\alpha_n=\frac{1}{10}$ and $\alpha_n=\frac{1}{n}$, respectively and put $\rho=\frac{1}{4}$ and $\beta_n= 0.8(1-0.8 e^{-\frac{n}{10}})$ in Algorithm 3.1 and 3.2. According to Theorem 3.1 and 3.2, the sequence $\{x_n\}$ generated by Algorithm 3.1 and 3.2 will converge to the element $x^*=P_{\mathcal{F}}x_1=(0,0,0)$. We will stop the program if $\|x_n\|<10^{-4}$. The following figures show the convergence of Algorithm 3.1 and 3.2 with the different initial point. \begin{figure}[h] \centering \subfloat {% \includegraphics[width=5.2in,totalheight=3.9in]{a1.eps}}\ \caption{ Convergence of Algorithm 3.1 and 3.2 with initial point $x_1=(3,2,10)$} \end{figure} \iffalse \section*{Acknowledgments} \vskip0.2cm This work is supported by Natural Science Foundation of Hebei Province (N0.

浮动体就是为了防止当插图大小不合适时,采用固定位置造成的**留白**的,应该相信LaTeX能够很好的处理浮动体。 如果觉得不爽,有两种方案:一是缩放插图到合适大小。二是精简文字留出地方或是添加废话把插图“挤到”下一页。 如果缩小后清晰度和字号等影响过大,那么就采用第2方案吧,精简和添加废话对能写论文的人来讲,都不是个事。 其实,完全可以不用太操心这些,有交叉引用,读者知道去哪里找这个插图。
