2023/1/5

转眼已经两个月没有更新这个系列了。

这之间发生了 NOIP,虽然没那么好,但也是我一年 OI 学习的反馈。

2023 年新的一年,虽然退役了,但我希望我能有一个新的开始。


规则:CF,随机一道题限时做(可用 C++ 语言提交),记录实际时间。
达到 \(30\) 升级,升级后分数为 \(0\)。

达到 \(-10\) 降级,降级后分数为 \(15\)。

若到达最低等级分数无限向下,最高等级同理。

做出 \(+\min\left(\mathrm{\dfrac{timelimit}{time+3\times penalty}}+1,4\right)\)

否则 \(-\max\left(\mathrm{penalty,4}\right)\)。

\(\mathrm{penalty}\):错误提交次数(不含 wa on 1)。

\(\mathrm{time}\):做题时间(含读题)。

\(\mathrm{timelimit}\):时间限制。

等级表(上下封顶)

难度区间 等级 颜色
\(1500\sim2000\) 伞兵 \(\color{#008000}\blacksquare\)
\(2000\sim2200\) 寻宝 \(\color{#03A89E}\blacksquare\)
\(2200\sim2400\) 不牛 \(\color{#3F48CC}\blacksquare\)
\(2400\sim2600\) \(\color{#920EF0}\blacksquare\)
\(2600\sim2800\) 牛大 \(\color{#FF8C00}\blacksquare\)
\(2800\sim3000\) 引荐人 \(\color{#FF0000}\blacksquare\)
  • 时间限制:若 \(x\) 为难度,\(\displaystyle \mathrm{timelimit}(x)=\dfrac{79}{3744000000}x^3-\dfrac{437}{4160000}x^2+\dfrac{18017}{93600}x-\dfrac{3455}{39}\)(分钟),四舍五入精确到秒

  • 暂停机制:必要时可暂停(包括反击男同,但不包括交流讨论等)。

  • 延时机制:无(不像某些人)。

  • 补题机制:结束前未通过,结束后补题,没看题解 \(+0.3\),看题解 \(+0.1\)。


\(\text{succ}\):表示是否在规定时间通过,\(\color{#28F078}{\surd}\) 表示通过,\(\color{red}{\times}\)。

\(\text{pass}\):表示是否补题,\(\color{#28F078}{\surd}\) 表示未看题解,\(\color{gray}{\surd}\) 表示看题解,\(\color{red}{\times}\) 表示未过。

\(\Delta\):向下取整保留 2 位小数。

\(\text{id/date}\) \(\text{prob}/\text{diff}\) \(\text{succ}\) \(\text{time}\) \(\text{pena}\) \(\text{pass}\) \(\text{rating}/\Delta\) \(\text{grade}\)

注意点

  1. -Wall,来源:38(1174F),输出函数指针。
    inline int S(...){
        ...
        cout<<S<<endl;
    }
    
  2. memcpy 类型不同,来源:44(1630D)。
    ll f[...];
    ...
    signed main(){
        for(...){
            int now=...,tmp[2];
            memcpy(tmp,f[now],sizeof tmp);
        }
    }
    

评价:

伞兵阶段评价:

感觉手速以及码力以及调题能力都有待提升。

寻宝阶段评价:

有一个明显的状态下降。

经历了 CSP。

在经历一番调整后,状态已经开始陆续回升。

码力其实稍微有所提升。但是调题能力不行。

基本上看到一个题都能秒,但是其中有一部分阿拉丁题,没救;还有一部分题,码力要求一般,但是就是硬是调了好久以至于失败。

CSP 只是秋游,NOIP 才是战斗。

希望各方面能继续提升。

另外,做诈骗题的能力也有待提升。
