Problem descriptionthere is a pile of N wooden sticks. the length and weight of each stick are known in advance. the sticks are to be processed by a woodworking machine in one by one fashion. it needs some time, called setup time, for the machine Prepare processing a stick. The setup times are associated with cleaning operations and changing tools and shapes in the machine. The setup times of the woodworking machine are given as follows: (A) The setu

''and W' are greater than or equal to L, and the values of'' and W' in sticks of W are the smallest stick. If it is in the original optimal solution, set up time is not required, after moving it to the stick (L, W) minimum, it will not be reduced or set up time will not be increased. If it needs to calculate the set up time in the original optimal solution, it must not be the optimal solution. Otherwise, after moving it to (L, W), a set up time can be reduced. In turn, we can get a certain opti

Question: calculate the maximum number of subsequences that do not increase in a sequence. Analysis: DP, Lis. The minimum number of non-ascending subsequences in a sequence is its maximum ascending subsequence length. Proof: First, find the Maximum ascending sub-sequence of the string, then each element must belong to a different non-descending string; If the first largest ascending subsequence is used, each element must be the maximum value in the set; The maximum values can be used to determin

Greed is a soft rib ...Do a good brush on the problem.Or we're going to blow up tomorrow.Let's all be greedy today.Well!Or the sort of a struct. (this thing is really useful!) ）Sort lengths from small to largeIf the length is equal then the weight is small in frontSelect the first node is not an initial nodeThen scan the side arraySee those nodes can be processed without processing timeMark it well.And then in sequential scan side arrayFind the first node without a tagDo the same scan again.Loop

At first glance, I knew it was the longest sequence without subtraction. I thought it was solved by using DP. But that is a wrong idea. I just moved for a long time. Then I looked at other people who could use DP, but it was hard to prove its correctness, and its speed was not fast. Therefore, it is not a good solution. So I directly calculate it, simulate and select the non-subtraction subsequence, and the answer is displayed after the selection. Ideas: 1. sort by length 2. Select the weig
