前几天一直在忙一些事情,所以一直没来得及开始这个搜索专题的训练,今天做了下这个专题的第一题,皇后问题在我没有开始接受Axie的算法低强度训练前,就早有耳闻了,但一直不知道是什么类型的题目,今天一看,原来是搜索题,还是入门的深搜题,关于题目的意思recwert在这就不解释了.直接讲讲思路吧. 按照深度优先搜索的理念,应该是从上到下搜索(如果你硬要说可以从下到上..但是仔细想想其实是一个意思..)在二叉树的DFS中,我们是假定了左孩子优先,所以在这题,我们也可以假定行优先(行优先和列优先是一个结果,…

NOIP2018提高组金牌训练营——搜索专题 1416 两点 福克斯在玩一款手机解迷游戏,这个游戏叫做”两点”.基础级别的时候是在一个n×m单元上玩的.像这样: 每一个单元有包含一个有色点.我们将用不同的大写字母来表示不同的颜色. 这个游戏的关键是要找出一个包含同一颜色的环.看上图中4个蓝点,形成了一个环.一般的,我们将一个序列 d1,d2,...,dk 看成一个环,当且仅当它符合下列条件时: 1.    这k个点不一样,即当 i≠j时, di 和 dj不同. 2.    k至少是4. 3.  …

搜索专题:Balloons 这道题一看与时间有关,第一想到的就是BFS,定义一个状态,包含每一个状态的剩余气球数,已经进行的时间和每一个志愿者上一次吹气球的时间: 每一次状态转换时,检查是否有没有使用的志愿者,或者是已经休息结束可以进行下一轮吹气球的志愿者,如果没有,就将进行的时间加一,进入下一个状态:第一次写的code超时,主要是没考虑最优结果,在还有志愿者可以使用的时候没有使用,而是又入一次队,导致无形中增加了无数的冗余状态: 代码如下: #include<iostream> #inclu…

我们已经知道mysql中带有"%keyword%"条件的sql是不走索引的,而不走索引的sql在大数据量+大并发量的时候,不仅效率极慢还很有可能让数据库崩溃.那我们如何通过某些关键字来搜索我们想要的文章呢? 虽然mysql的MYISAM提供全文索引,但是只支持中文,并且性能却不敢让人恭维,因此采用Sphinx来做mysql的全文索引工具是一个很好的选择. 简介 Sphinx是由俄罗斯人Andrew Aksyonoff开发的一个全文检索引擎.意图为其他应用提供高速.低空间占用.高结果 相…
