最优平行轨道车皮排序问题
.问题描述:
在一个列车调度站中,k 条轨道平行连接到1 条侧轨处,形成1 条主轨道和k-1 条辅助
调度轨道。主轨道记为Hk,辅助轨道从下到上依次记为H1,H2,…,Hk-1 如下图所示。其
中主轨道左边为车皮入口(记为H0),主轨道右边为出口(仍记为Hk)。编号为a1, a2,L,an
的n 个车皮从入口依次进入主轨道,由调度室安排车皮进出轨次序,并对车皮按其出轨次序
重新排序为1,2,…,n。
调度室在安排车皮进出轨次序时,遵循以下规则:
(1)
车皮入口H0 处的车皮可以进入辅助轨道H1,H2,…,Hk-1 之一,或直接进
入车皮出口Hk。
(2)
辅助轨道H1,H2,…,Hk-1 处的车皮可以进入车皮出口Hk。
.编程任务:
给定正整数n,和n 个车皮的初始编号a1, a2,L,an ,编程计算最少需要多少个平行轨
道才能按照规则(1)和(2)调度车皮,使车皮在车皮出口按照1,2,…,n 的顺序输出。
.数据输入:
由文件input.txt 给出输入数据。第1 行有1 个正整数n,表示有n 个车皮。第2 行是n
个车皮的初始编号a1, a2,L,an 。
.结果输出:
将计算出的最少平行轨道数输出到文件output.txt 。-optimal parallel tracks wagon scheduling problem.
