An automatic routing program system for the wiring of multilayer printed circuit boards is presented, The system employs the iterative placement algorithm and improved Lee's routing algorithm. 此文介绍多层印制底板自动布线系统DBX2,此系统有人工布局和自动布局,布线算法有改进的李氏迷路法和最小费用布线法。
In order to overcome this drawback, Lee proposed a modified FCM algorithm-Lee's algorithm. 针对这种情况,Lee于1994年提出了一种所谓的改进模糊C均值算法_Lee's算法。
