说明：   德州仪器(TI)宣布推出业界首款带硬件定位引擎的片上系统(SoC)解决方案 CC2431，以 满足低功耗 ZigBee/IEEE802.15.4 无线传感器网络应用的需求。这款来自 Chipcon 产品系列 的器件可满足多种应用要求，其中包括资产和设备跟踪、库存控制、病患监护、远程控制、 安全监控网络等应用，此外，TI领先的 ZigBee协议栈 Z-Stack 还提供有关支持。 CC2431 建立在业界首款针对低功耗 RF 应用的 SoC 解决方案 CC2430 的基础之上。上 述两款器件将业界领先的CC2420 RF收发器内核与增强型8051微控制器的出色性能完美结 合，具有高达 128kB 的闪存、8kB的 RAM 以及许多附加功能，而这一切仅采用一个 7 毫米 x7 毫米小型封装就实现了。 CC2431基于RSSI(Received Signal Strength Indicator)的定位引擎能根据接收信号强度与 已知 CC2430参考节点位置准确计算出有关节点位置，然后将位置信息发送给接收端，如电 脑、PDA、手机等。相比于集中型的定位系统，RSSI 功能降低了网络流量与通信延迟，在 典型应用中可实现 3 至5 米的精度。 (The CC2431 is a true System-On-Chip (SOC) for wireless sensor networking ZigBee™ / 802.15.4 solutions with location detection engine hardware onboard allowing location accuracy of around 3 meters or less. It enables ZigBee™ nodes to be built with very low total bill-of-material costs. The CC2431 combines the excellent performance of the leading CC2420 RF transceiver with an industry-standard enhanced 8051 MCU, 128 KB flash memory, 8 KB RAM and many other powerful features. Combined with the industry leading ZigBee™ protocol stack (Z-Stack™ ) from Figure 8 Wireless/Chipcon, the CC2431 provides the market’s most competitive ZigBee™ solution. The CC2431 is highly suited for systems where ultra low power consumption is required. This is achieved by various operating modes. Short transition times between these modes further ensure low power consumption. )

分支定界法（branch and bound）是一种求解整数规划问题的最常用算法。这种方法不但可以求解纯整数规划，还可以求解混合整数规划问题。分支定界法是一种搜索与迭代的方法，选择不同的分支变量和子问题进行分支。(Branch and bound (branch and bound) is one of the most commonly used algorithms for integer programming problems. This method can not only solve pure integer programming, but also solve mixed integer programming problems. Branch and bound is a search and iterative method, which selects different branch variables and sub problems to branch.)
