为了自己想要的未来,无论现在有多难熬,都必须得满怀信心地坚持下去。 ​​​​——江老师2018.1.7

你的水平不取决于你解决了多少个题,而是取决于你是如何思考的。当你试图去解决一个问题时,你应该先独立思考。如果你实在没有思路,那么你应该去一点一点的读别人的题解,而不是一次性都读完,尽可能确保能有更多的部分是你自己做出来的。之后,仔细思考下,为什么你会想不出来依赖于题解解决的那些部分。千万别抄别人的代码,每个人都有他独特的解题理解方式——毛啸。

长期任务:

  • 订正JSOI2018以及各次考试
  • 字符串(KMP,AC自动机,后缀数组,后缀自动机)
  • 平衡树(Treap,Splay,替罪羊树,finger tree)
  • dp优化(一单调队列,四边形不等式即决策单调性,斜率优化)以及各类dp(一般的线性dp和区间dp,树形,状压含子集dp、斯坦纳树、插头dp,数位dp,概率期望,组合计数)
  • 网络流(主要是建模,也可以学学一些更优的模板)
  • 图论(主要是思想方法,以及延伸出的2-SAT和差分约束)
  • 数学(以《训练指南》第二章为主,还有积性函数与莫比乌斯反演,多项式FFT、NTT、MTT,矩阵)
  • 计算几何基础
