[NOIP2006 提高组] 作业调度方案(修改)

发布时间:2024年01月11日

题目:

这里对于之前的题目进行修改记录。果然还是受不了等待,利用晚饭时间又看了这个题目。于是发现了问题。
之前的博客:https://blog.csdn.net/KLSZM/article/details/135522867?spm=1001.2014.3001.5501


问题修改描述

上午书写的代码中是按照工件的顺序号依次遍历,就是先将工件1的所有工序都放置完成后再进行下一个工件的录入。但是忽略了题目中所给出的顺序。所有的工件顺序在题目中已经给出。我们只需要放置好以后再抽空插入即可,修改了代码还是有一个测试点没有通过。后来下载了数据才发现是这个点的数据有问题!
以下是修改后的py代码

class Work:
    def __init__(self,n):
        self.num=n
        self.order_machine=[]
        self.time_machine=[]
        self.final=-1
        self.num_now=0


def judge(t,x,y):
    global wore_line
    for i in range(x,x+y):
        if wore_line[t][i]!=0:
            return False
    return True


def add(t,x,y,p):
    global wore_line
    for i in range(x,x+y):
        wore_line[t][i]=p


if __name__=="__main__":
    num__max=120
    m, n = map(int, input().split())
    wore_line = [[0]*num__max for _ in range(m)]
    mapp = input()
    mapp=[int(intt) for intt in mapp.split()]
    work = []
    for item in range(2 * n):
        data = list(map(int, input().split()))
        if item < n:
            work.append(Work(item + 1))
            for k in range(m):
                work[item].order_machine.append(data[k])
            # work[item].order_machine = data
        else:
            for k in range(m):
                work[item-n].time_machine.append(data[k])
            # work[item - n].time_machine = data
    flag=True
    step=0
    while flag:
        num_piece=mapp[step]-1
        num_piece_order=work[num_piece].num_now
        key_machine=work[num_piece].order_machine[num_piece_order]
        key_time=work[num_piece].time_machine[num_piece_order]
        # print("%d-%d:%d"%(num_piece+1,num_piece_order+1,key_time))
        for item in range(num__max-key_time):
            if judge(key_machine-1,item,key_time) and item>work[num_piece].final:
                add(key_machine-1,item,key_time,num_piece+1)
                work[num_piece].final=item+key_time-1
                break
        # for item in range(m):
        #     print(wore_line[item])
        # print()
        work[num_piece].num_now+=1
        step+=1
        if step==n*m:
            flag=False
    # for item in range(m):
    #     print(wore_line[item])
    # print()
    time_max=0
    time=0
    for item in range(m):
        for jtem in range(num__max-1,0,-1):
            if wore_line[item][jtem]!=0:
                time=jtem+1
                break
        if time_max<time:
            time_max=time
    print(time_max)

请添加图片描述
第七个点的数据如下:

8 9
2 8 8 4 7 2 6 3 9 3 3 2 1 6 5 5 9 9 6 8 2 8 9 7 1 3 3 6 7 6 9 3 5 1 7 2 4 3 8 1 4 1 4 6 8 9 4 6 6 7 2 5 2 7 9 4 4 1 1 5 2 5 4 1 7 5 8 5 7 8 3 9 
1 2 3 4 5 6 7 8
1 2 4 5 6 7 8 3
3 4 5 6 7 8 1 2 
5 6 7 8 1 2 3 4
4 5 6 7 1 2 3 8
1 2 3 4 8 7 6 5
1 2 4 3 5 6 8 7
3 4 5 6 7 8 1 2
4 5 3 2 1 6 7 8
5 6 7 8 9 10 3 4
9 3 5 6 7 8 10 4
10 3 9 5 1 5 6 7 
14 5 9 8 3 5 10 7
12 5 6 7 8 9 4 7
5 6 7 8 9 13 4 2 10
5 6 7 8 9 3 4 10
10 12 13 4 5 6 7 8
4 5 6 3 2 10 7 6

结果应是116,我得出的是112

通过对比可以发现,第七个工件的第一道工序的时间应该是10,而我的却是5.但是在输入中确实是5
在看一下输入数据,可以看到,第六个工件的数据为:

5 6 7 8 9 13 4 2 10

是9个数据.
这是不符合输入m=8的规矩的。而多输入的数据正好又是10,所有我认为应该是输入错误了。我一开始是直接将数据存入结构体中。但是发现修改成强制输入m组数据运行出来也是错的。。。


解决方案:

兄弟们这种数据这么离谱,咱不要自我折磨,直接跳过这组数据(狗头)

        for item in range(m):
            for jtem in range(num__max - 1, 0, -1):
                if wore_line[item][jtem] != 0:
                    time = jtem + 1
                    break
            if time_max < time:
                time_max = time
        print(time_max)
