好的，这里有一种方法可以做到。

步骤 1：我禁用了所有软件包，然后包含这些软件包，这样文件就可以编译了

Question 3

本回答包含以下内容：

一些针对 LaTeX 新手的背景知识
使 JCST 模板编译
用一些演示内容填充它，包括盲文和文本
最后的建议

LaTeX 新手背景

正如您所写，这是您第一次使用 LaTeX。刚开始使用 LaTeX 时可能会感到困惑。从面向布局的程序（如微软Word，Adobe Acrobat，画框制作师或者抄写员一种是经过预先训练的，可以同时处理内容（说什么）和布局（在哪里放置什么）。

LaTeX 则不同：只要你说出你的想法（文本），它就会把东西“整齐地”放在它能找到的空间里。这是最初的想法。现在，作者喜欢时不时地影响布局。这就是为什么环境（如图片）会为 LaTeX 提供一些布局建议。专用软件包甚至更进一步。

作为一种策略，尝试在 JCST 的模板世界中工作。依靠“这就是他们希望它在印刷品中看起来的样子”。

如果你还没有这样做，我建议你找一些关于 LaTeX 介绍的书，或者浏览一下并在里面搜索关于 LaTeX 的维基教科书。您可以在此网站上找到更多关于介绍材料的提示。

查找包裹总是一个好主意加拿大运输安全局并阅读其手动的。

使 JCST 模板编译

因此，要回答你的问题差距和算法我的第一步是从您提供的链接下载 JCST 模板并进行编译。它的前言部分与您最初发布的代码也略有不同。编译时出现了一些小问题。

作为一般规则，搜索骨髓移植在下面的代码中，我把我的评论放在那里。

picins(1991) 似乎已经过时了。例如，它将用于在末尾包含作者照片。我将其排除在外。此外，包picinpar不起作用（\hsize 错误）。因此，除非您计划在内容中包含更多图像，否则您可能可以将其留给 JCST 发布。

软件包algorithm和algoritmic似乎不再存在于 CTAN 上。虽然我的发行版控制台正在尝试安装它们，但我决定使用algorithm2e它们提供的选项。强烈建议在手册中检查其使用和选项。

包lipsum只是为了演示目的而填写一些盲文。

我有意保留了有关作者、关键词等的所有内容，因为您接受的论文稍后也会占用这个空间。（调整后的）页脚也是如此。

内容示例

您将看到，我从 JCST 模板中删除了内容（仅删除了那些部分）。我使用了\section{}和\subsection{}来为该演示内容提供基本结构。

对于“1 简介”，我只放置了一些\lipsum语句并插入了一个算法，从手动的：

第一个带有选项 [H] 的版本（放在这里（如果可能））
第二个版本没有选项，即让它浮动（当你改变内容时它会移动）

除此之外，我\label{}在这两个\caption语句中都添加了一个，以便您以后可以参考文本中的算法。关于这一点有几件事：

命名是自由的；我决定使用alg:N，其中 N 是一个数字；名字可能更好，例如alg:someHint
LaTeX 会自行处理编号，这就是为什么使用alg:N可能会随着时间的推移而变得令人困惑，并且alg:Name可能更好
你不必遵循这个方案，但它可以帮助你避免错误；当你的内容增长时，tab:anOverview参见例如等fig:aNiceCurve

要引用这些标签，请\ref{}在运行文本中使用。有关示例的详细信息，请参阅“2 详细信息”，包括印刷版和代码版。例如，您稍后可以将表格引用为\ref{tab:anOverview}，而 LaTeX 会在编译期间将其替换为表格的正确编号。

请注意，LaTeX 需要两次编译运行才能放置正确的值（第一次运行：编译，第二次运行：替换找到的内容）。

从截图中你可以看到一些特点：

p. 2 “偶然”浮动算法是你放置它的地方；它可能会四处移动
LaTeX 放置算法很好地平衡了两个（未完成的）列，当你编辑更多内容时，这种情况会发生变化

再次检查algorithm2e手册，它告诉你如何处理例如：

更长的算法
“分页符”
a-col、2-col 跨度
\;何时在伪代码行中使用
ETC。

最后的建议

复制我的代码并将我的内容替换为您的（% ~~~ MS-SPO：这里开始您的内容~~~~~~~~~~）。不要在意其他部分，让内容暂时自由流动。编辑过程中会出现间隙。一旦快完成，请专注于内容并进行“位置”调整。

Answer

本回答包含以下内容：

一些针对 LaTeX 新手的背景知识
使 JCST 模板编译
用一些演示内容填充它，包括盲文和文本
最后的建议

LaTeX 新手背景

正如您所写，这是您第一次使用 LaTeX。刚开始使用 LaTeX 时可能会感到困惑。从面向布局的程序（如微软Word，Adobe Acrobat，画框制作师或者抄写员一种是经过预先训练的，可以同时处理内容（说什么）和布局（在哪里放置什么）。

LaTeX 则不同：只要你说出你的想法（文本），它就会把东西“整齐地”放在它能找到的空间里。这是最初的想法。现在，作者喜欢时不时地影响布局。这就是为什么环境（如图片）会为 LaTeX 提供一些布局建议。专用软件包甚至更进一步。

作为一种策略，尝试在 JCST 的模板世界中工作。依靠“这就是他们希望它在印刷品中看起来的样子”。

如果你还没有这样做，我建议你找一些关于 LaTeX 介绍的书，或者浏览一下并在里面搜索关于 LaTeX 的维基教科书。您可以在此网站上找到更多关于介绍材料的提示。

查找包裹总是一个好主意加拿大运输安全局并阅读其手动的。

使 JCST 模板编译

因此，要回答你的问题差距和算法我的第一步是从您提供的链接下载 JCST 模板并进行编译。它的前言部分与您最初发布的代码也略有不同。编译时出现了一些小问题。

作为一般规则，搜索骨髓移植在下面的代码中，我把我的评论放在那里。

picins(1991) 似乎已经过时了。例如，它将用于在末尾包含作者照片。我将其排除在外。此外，包picinpar不起作用（\hsize 错误）。因此，除非您计划在内容中包含更多图像，否则您可能可以将其留给 JCST 发布。

软件包algorithm和algoritmic似乎不再存在于 CTAN 上。虽然我的发行版控制台正在尝试安装它们，但我决定使用algorithm2e它们提供的选项。强烈建议在手册中检查其使用和选项。

包lipsum只是为了演示目的而填写一些盲文。

我有意保留了有关作者、关键词等的所有内容，因为您接受的论文稍后也会占用这个空间。（调整后的）页脚也是如此。

内容示例

您将看到，我从 JCST 模板中删除了内容（仅删除了那些部分）。我使用了\section{}和\subsection{}来为该演示内容提供基本结构。

对于“1 简介”，我只放置了一些\lipsum语句并插入了一个算法，从手动的：

第一个带有选项 [H] 的版本（放在这里（如果可能））
第二个版本没有选项，即让它浮动（当你改变内容时它会移动）

除此之外，我\label{}在这两个\caption语句中都添加了一个，以便您以后可以参考文本中的算法。关于这一点有几件事：

命名是自由的；我决定使用alg:N，其中 N 是一个数字；名字可能更好，例如alg:someHint
LaTeX 会自行处理编号，这就是为什么使用alg:N可能会随着时间的推移而变得令人困惑，并且alg:Name可能更好
你不必遵循这个方案，但它可以帮助你避免错误；当你的内容增长时，tab:anOverview参见例如等fig:aNiceCurve

要引用这些标签，请\ref{}在运行文本中使用。有关示例的详细信息，请参阅“2 详细信息”，包括印刷版和代码版。例如，您稍后可以将表格引用为\ref{tab:anOverview}，而 LaTeX 会在编译期间将其替换为表格的正确编号。

请注意，LaTeX 需要两次编译运行才能放置正确的值（第一次运行：编译，第二次运行：替换找到的内容）。

从截图中你可以看到一些特点：

p. 2 “偶然”浮动算法是你放置它的地方；它可能会四处移动
LaTeX 放置算法很好地平衡了两个（未完成的）列，当你编辑更多内容时，这种情况会发生变化

再次检查algorithm2e手册，它告诉你如何处理例如：

更长的算法
“分页符”
a-col、2-col 跨度
\;何时在伪代码行中使用
ETC。

最后的建议

复制我的代码并将我的内容替换为您的（% ~~~ MS-SPO：这里开始您的内容~~~~~~~~~~）。不要在意其他部分，让内容暂时自由流动。编辑过程中会出现间隙。一旦快完成，请专注于内容并进行“位置”调整。
