latex tips

\advance\leftskip-1cm  move figure to the left

如何用texstudio:
1. 直接打开主文件，会自动识别所有相关的文件的。
2. overleaf上面是bib 文件，本地的是bbl文件，overleaf 的生成bbl 文件需要点击log 按钮，拉到最下面，会有一个下载bbl 文件的地方。
3. citation undefined warning 解决方法：I know that this question has been answered here Undefined citation warnings, which states that the user should compile the code with the following process:

1. latex
2. bibtex
3. latex
4. latex

对应的命令行为 pdflatex ijcai19; bibtex ijcai19
