To do List:
- 一有空就训练
- POI2018 Stage I【Done】
战术研究:
- 读新题的优先级高于一切
- 读完题之后必须看一遍clarification
- 交题之前必须看一遍clarification
- 可能有SPJ的题目提交前也应该尽量做到与样例输出完全一致
- WA时需要检查INF是否设小
- 构造题不可开场做
- 每道题需至少有两个人确认题意
- 上机之前做法需得到队友确认
- 带有猜想性质的算法应放后面写
- 当发现题目不会做但是过了一片时应冲一发暴力
- 将待写的题按所需时间放入小根堆中,每次选堆顶的题目写
- 交完题目后立马打印随后让出机器
- 写题超过半小时应考虑是否弃题
- 细节、公式等在上机前应在草稿纸上准备好,防止上机后越写越乱
- 提交题目之前应检查$solve(n,m)$是否等于$solve(m,n)$
- 检查是否所有东西都已经清空
- 对于中后期题应该考虑一人写题,另一人在一旁辅助,及时发现手误
- 最后半小时不能慌张
- 对于取模的题,在输出之前一定要再取模一次进行保险
- 对于舍入输出,若$abs$不超过$eps$,需要强行设置为$0$来防止$-0.0000$的出现。
打表找规律方法:
- 直接找规律
- 差分后找规律
- 找积性
- 点阵打表
- 相除
- 找循环节
- 凑量纲
- 猜想满足$P(n)f(n)=Q(n)f(n-2)+R(n)f(n-1)+C$,其中$P,Q,R$都是关于$n$的二次多项式
