Lampposts ACM解题报告(dp)
//这题就是一个森林,每次都找根节点,然后往子节点查找,这题的关键是要设一个公式ans=Ma+c,其中a是点的灯数,b是两个灯照的边数,c是一个灯照的边数,因为a需要最小,b需要尽可能大,所以c就是尽可能小,也就是ans要尽可能小,一般来说,如果有两个需要优化的量a和b,要求首先满足a最小,然后在a相同的情况下b最小,则可以把两者组合成一个量Ma+b,M是一个比b的最大理论值和b的最小理论值之差还

树形DP。子问题可以分为两类,即在u为根节点且在u点放置灯时的最小灯数、u为根节点且不在u点放置灯时的最小灯数。这样用dp【u】【1】,dp【u】【0】分别表示这两种情况。用edge【u】【0/1】【1/2】表示这两种情况时同时被灯照亮一条边、两条边的个数。dp【u】【0】可以由u的所有子节点的dp【i】【1】之和转移而来,即当该结点的所有子节点都放灯时,这个点可以不放灯。同时计算edge【u】【

这个题属于树形DP题,算是第二次做吧,也算是学习。看了书上写的策略,理解了半天总算明白了。其实有2个策略:策略1:结点j不放灯。必须j=1或者是i是根结点时才允许作这个决策。此时dp(i,j)等于sum{d(k,0)|k取遍历i的所有子结点}。如果i不是根,还得加上1,因为结点i和其父亲结点这条边上只有一盏灯照亮。策略2:结点i放灯。此时dp(i,j)等于sum{dp(k,1)|k取遍i的所有子结
