We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

在工业生产和科学技术研究的各行业中,常常利用PC或工控机对各种数据进行采集。这其中有很多地方需要对各种数据进行采集,如液位、温度、压力、频率等。现在常用的采集方式是通过数据采集板卡,常用的有A/D卡以及422、485等总线板卡。采用板卡不仅安装麻烦、易受机箱内环境的干扰,而且由于受计算机插槽数量和地址、中断资源的限制,不可能挂接很多设备。而通用串行总线(Universal Aerial Bus,简称USB)的出现,很好地解决了以上这些冲突,很容易就能实现低成本、高可靠性、多点的数据采集。
