For the incomplete methods, we kept the representation of the queens by a table and the method of calculation to determine if two queens are in conflict, which is much faster for this kind of problems than the representation by a matrix. heuristics: descent. Tests: 100 queens in less than 1 second and 67 iterations. 500 queens in 1 second and 257 iterations. 1000 queens in 11 seconds and 492 iterations. heuristics: Simulated annealing. Tests: 100 queens in less than 1 second and 47 iterations. 500 queens in 5 seconds and 243 iterations. 1000 queens in 13 seconds and 497 iterations. heuristics: based on Simulated Annealing. Tests: 100 queens in less than 1 second and 60 iterations. 500 queens in 1 second and 224 iterations. 1000 queens in 5 seconds and 459 iterations. 10 000 queens in 20 minutes 30 seconds and 4885 iterations.

People have vast background knowledge to cope with everyday situations. We don t have to be told everything explicitly because we can call on the background knowledge. We use `default knowledge to handle situations where knowledge is incomplete. This is called common sense reasoning.

学习本章要达到的目标：口1.理解 Linux内核编译选项的含义口2.学会根据不同的硬件配置裁减定制内核；口3.理解内核编译过程中每一步的功能，并编译 Linux2.630内核。需要去重新编译 Linux内核口增加操作系统对新的硬件设备的支持口增加内核新的功能口对内核代码或内核配置进行优化时Prompt for development and/or incomplete code/drivers口显示处于开发调试中或尚未完善的代码或驱口选中：如果是测试人员或者开发者；口不选：其他情况Local version append to kerne release口追加本地版本号口使用命令“uname-a”进行查看。POSIX Message Queues口 POSIX消息队列的支持，这是 POSIX进程间通信的一部分BSD Process Accounting口将进程的统计信息写入文件口信息通常包括建立时间、所有者、命令名称、内存使用、控制终端等，这个选项一般是选择的。Enable loadable module support口使能可加载模块支持口如果使能此选项则可以通过"makemodules_insta"把内核模块安装在/lib/modules/中Kernel support for ELF binaries口内核对ELF文件格式的支持口ELF是开放平台下最常用的二进制文件格式支持动态连接，支持不同的硬件平台Kernel support for a out and ECOFF binaries口早期UNIX系统的可执行文件格式，目前已经被ELF格式取代Unix domain sockets口本机高效率的 Socket口仅能运行在本机上的高效率的 Socket，简称 Unix socket。口很多进程使用为这种机制在操作系统内部进行进程间通信，例如 X Window和 syslog等TCP/IP networking口TcP/IP网络协议的支持
