循环赛日程表(分治法)
5星 · 资源好评率100%
循环赛日程表的分治算法通常用于解决体育比赛安排的问题,比如田径、自行车等项目的赛事时间安排。这种算法通过将大问题分解成小问题并递归地解决它们,最后合并结果。这里提供一个简单的伪代码示例,实际语言如Python可能会有所不同:
```python
def schedule_tournaments(tournaments, n_days):
# 如果只有一个比赛,直接返回
if len(tournaments) == 1:
return [tournaments[0]]
# 将比赛分为两半
half = len(tournaments) // 2
left_half = tournaments[:half]
right_half = tournaments[half:]
# 分别对左右两组进行排程
left_schedule = schedule_tournaments(left_half, n_days)
right_schedule = schedule_tournaments(right_half, n_days)
# 合并两个半程的日程
combined_schedule = merge_schedules(left_schedule, right_schedule, n_days)
return combined_schedule
def merge_schedules(schedules, rest_schedules, n_days):
result = []
for i, schedule in enumerate(schedules):
while rest_schedules and n_days > 0:
next_schedule = rest_schedules.pop(0)
if can_fit(schedule, next_schedule):
result.append((schedule, next_schedule))
n_days -= 1
else:
break
result.extend(rest_schedules)
return result
# 检查是否能在给定天数内安排两个比赛
def can_fit(schedule1, schedule2):
return max(schedule1.end_date, schedule2.start_date) <= n_days
# 示例:
tournaments = ... # 赛事列表
n_days = ... # 总共可用天数
schedule = schedule_tournaments(tournaments, n_days)
```
注意:这个代码仅给出基本框架,并未包括错误处理和边界条件检查。在实际应用中,需要完善代码以处理各种复杂情况。
