如何使用minipage或subfigure将两个algorithm2e（一个大，一个小）并排放置？

Question

我有两个用 algorithm2e 包编写的算法。其中一个很大，另一个很小。我的尝试如下：

\documentclass{article}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{amsmath}
\usepackage[noline]{algorithm2e}

上述结果是： 对我来说，它们两个看起来都不太好。我想要

1. 代码行不会分成两行。
2. 注释将与代码位于同一行。
3. 这些算法的标题是对齐的。

我想要的是：

Answer 1

下面我使用了两个minipages，每个算法一个，后面又使用了两个minipages，每个算法标题一个。需要重复使用才能实现适当的对齐。
