“连连看”相信很多人都玩过。没玩过也没关系，下面我给大家介绍一下游戏规则：在一个棋盘中，放了很多的棋子。如果某两个相同的棋子，可以通过一条线连起来（这条线不能经过其它棋子），而且线的转折次数不超过两次，那么这两个棋子就可以在棋盘上消去。不好意思，由于我以前没有玩过连连看，咨询了同学的意见，连线不能从外面绕过去的，但事实上这是错的。现在已经酿成大祸，就只能将错就错了，连线不能从外围绕过。 玩家鼠标先后点击两块棋子，试图将他们消去，然后游戏的后台判断这两个方格能不能消去。现在你的任务就是写这个后台程序。

来源：Deephub Imba本文约4800字，建议阅读10分钟本文中我们将使用遗传算法在迷宫中找到最短路径。 遗传算法是一种基于达尔文进化论的搜索启发式算法。该算法模拟了基于种群中最适合个体的自然选择。 遗传算法需要两个参数，即种群和适应度函数。根据适应度值在群体中选择最适合的个体。最健康的个体通过交叉和突变技术产生后代，创造一个新的、更好的种群。这个过程重复几代，直到得到最好的解决方案。 要解决的问题 本文中我们将使用遗传算法在迷宫中找到最短路径。 本文的的路径规划基于论文Autonomous

Initially there are nn integers a1,a2,…,ana1,a2,…,an written on the board. Each turn a player selects one number and erases it from the board. This continues until there is only one number left on the board, i. e. n−1n−1 turns are made. The first player makes the first move, then players alternate turns.

This is the Computer Systems A summative coursework. The coursework is worth 80% of the unit mark. It is to be completed in your programming pairs. You must report any change to your pairing to the unit director before starting your assignment. It runs over 4 weeks (5 weeks including the reading week) and the deadline for submitting all your work is Friday 3rd December 13:00.
You are given n switches and m lamps. The i-th switch turns on some subset of the lamps. This information is given as the matrix aconsisting of n rows and m columns where ai, j = 1 if the i-th switch turns on the j-th lamp and ai, j = 0 if the i-th switch is not connected to the j-th lamp.

The TX5121 is a step-up DC/DC converter specifically designed to drive up to 6 series white LEDs with constant current. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. The TX5121 switches at 1.4MH z, allowing the use of tiny external components. A low 0.25V feedback voltage minimizes power loss in the current setting resistor for high efficiency. The OVP pin monitors the output voltage and turns off the converter whenever the LEDs are open. The TX5121 is available in low profile SOT-23-6 package.
