This is the last 每周一题. I started it because I noticed that there are very few problems that are both interesting and challenging. (Sorry to say that most problems are neither.) It was very well received in the beginning, introduced some nice discussions and even some similar problems. But soon the enthusiasm faded and the later problems were largely ignored by all. There are some possible reasons:
1) People do not like difficult problems. This is true everywhere, especially when there is no monetary award.www.ddhw.com
2) Visitors here already know the problems. I doubt about this because we have already seen that most people are eager to respond to problems they knew the answer.
3) The prolems are falling too fast on the list and most people have not noticed them.
No matter what the reason is, there is no point to continue. So it will end now. www.ddhw.com
"终于不怎么去情趣生活了": I don't understand your reason behind it. You are still here. Do you seriously believe people and problems here are better than 万精油 and 情趣生活?
"我还是经常看其他人怎么解答你出的题目": You really do not have much to see when nobody does them.
To block blue side from connecting through the board, then red should have a connected through line. Same is true for the blue to block the red. Therefore, there is no tie in this kind of game. If red succesfully block blue from forming a through connection, then red will have a cross connection.
Thanks for your support. I just don't know whether anybody actually read them. It happened many times the problem falling very fast to the second page and lost.www.ddhw.com
Thanks for all the support. It looks like the problem exists everywhere. At WXC 禾牛also announced the end of his 每周一题, due to the lack of interests. The following is copied from 情趣生活, posted today by 万精油:
I think these are very good suggestions. And I would add a little more here:
1. For difficult problems, I suggest 新用户版主 to put them in lead so more people can see them.

2. If you are thinking about a difficult problem, post whatever idea or progress you may have. It may help other people who are also thinking about it, or other people may tell you whether the idea is in the right direction.
3. If you know the answer, and feel that other people may need a little help, post a hint.
4. Even if you have no idea at all, you may ask the original poster for some hints, so he/she knows that someone it still thinking about it.www.ddhw.com
Finally, I will post answers to the old problems when they are reposted by 新用户. Also this column will resume if most of you like it, after the current problems are dealt with.
