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).

RS-485串行总线接口标准以差分平衡方式传输信号,具有很强的抗共模干扰的能力,允许一对双绞线上一个发送器驱动多个负载设备。工业现场控制系统中一般都采用该总线标准进行数据传输,而且一般采用RS-485串行总线接口标准的系统都使用8044芯片作为通信控制器或各分机的CPU。8044芯片内部集成了SDLC,HDLC等通信协议,并且集成了相应的硬件电路,通过硬件电路和标准协议的配合,使系统的通讯准确、可靠、快速。8044在市场上日渐稀少,虽然有8344可替代,但几百元的价位与普通单片机几元至几十元的价位相差甚远,用户在开发一般的单片机应用系统时,都希望能用简单的电路和简单的通信协议完成数据交换。譬如:利用单片机本身所提供的简单串行接口,加上总线驱动器如SN75176等组合成简单的RS-485通讯网络。本文所述的方法已成功地应用于工程项目,一台主机与60台从机通讯,通讯波特率达64KBPS。
