## 基本用法 ##

### 步骤1：导入需要的算法包。 ###

\usepackage[ruled,vlined]{algorithm2e}

### 步骤2：具体算法。 ###

\begin{algorithm}[t]
    	\caption{Framework of Meta-GNN.}
    	\label{alg:algorithm1}
    	\KwIn{Distribution over mete-training tasks: $p(\mathcal{T})$; Meta-testing tasks: $\mathcal{T}_{mt}$; Task-learning rate: $\alpha_{1}$; Meta-learning rate: $\alpha_{2}$.}
    	\KwOut{Labels of nodes in query set of $\mathcal{T}_{mt}$.}  
    	\BlankLine
    	Initialize $\bm{\theta}$ randomly;
    	
    	\While{\textnormal{not converged}}{
    		Sample batch of meta-training tasks $\mathcal{T}_{i} \sim p(\mathcal{T})$;
    		
    		\ForEach{task in $\mathcal{T}_{i}$}{
    			Evaluate $\mathcal{L}_{\mathcal{T}_{i}}\left(f_{\bm{\theta}}\right)$ using $\mathcal{S}_{i}$;
    			
    			Compute adapted parameters $\bm{
       {\theta}^{\prime}_{i}}$;
    			
    			Evaluate $\mathcal{L}_{\mathcal{T}_{i}}\left(f_{\bm{
       {\theta}_{i}^{\prime}}}\right)$ using $\mathcal{Q}_{i}$;
    		}
    		Update $\bm{\theta}$ by; 
    	}
    	
    	Compute adapted parameters $\bm{
       {\theta}^{\prime}_{mt}}$ using support set of $\mathcal{T}_{mt}$; 
    	
    	Predict labels of nodes in query set of $\mathcal{T}_{mt}$ using model $f_{\bm{
       {\theta}_{mt}^{\prime}}}$.
    	
    
    \end{algorithm}

算法的标题

\caption{Framework of Meta-GNN.}

算法的标签，方便在文章中引用，例如

\label{alg:algorithm1}

Algorithm~\ref{alg:algorithm1}

算法的输入

\KwIn{Distribution over mete-training tasks: $p(\mathcal{T})$; Meta-testing tasks: $\mathcal{T}_{mt}$; Task-learning rate: $\alpha_{1}$; Meta-learning rate: $\alpha_{2}$.}

算法的输出。

\KwOut{Labels of nodes in query set of $\mathcal{T}_{mt}$.}

## 备注： ##

### (1).如果想要给算法的步骤加上序号： ###

这样引入包：

\usepackage[ruled,linesnumbered]{algorithm2e}

效果如下：

### (2). 某些步骤加颜色： ###

首先引入包：

\usepackage{color}

然后修改其中一句

{\color{red}Evaluate $\mathcal{L}_{\mathcal{T}_{i}}\left(f_{\bm{
       {\theta}_{i}^{\prime}}}\right)$ using $\mathcal{Q}_{i}$;}

实际效果：
