算法伪代码是论文的核心之一.

1. 需要说明输入、输出;
2. 方法 (函数) 名可写可不写, 如果被别的方法调用就必须写;
3. 需要写出主要步骤的注释;
4. 长度控制在 15-30 行;
5. 可使用数学式子或对已有数学式子的引用;
6. 不重要的步骤可以省略;
7. 一般需要进行时间、空间复杂度分析, 并写出配套的 property 以及相应的表格, 以使其更标准.
8. 在正文中分析伪代码的时候, 对多行引用应该用双连词符, 它会转成一个较长的连词符. 如: Lines 3–4 shows. Tables 4–6 同理. 两个并行的词连接起来 (等价词的复合), 也应该用 Serial–parallel. 参考文献的页码也应该用双连词符 pp. 87–99. multi-label 这里有个从属关系, 就应该用单连词符.
