But here is the (very) quick and (very) dirty python code if someone is interested.
There is very likely much easier/better ways to do it, but the below did what I wanted.
Note that it is quite hardcoded to do the Swedish First Division/HockeyEttan at the moment.
But feel free to use it in anyway you like.
Code: Select all
#!env python3
import copy
import random
# See way below for start of script
def generate_schedule(matches):
schedule = ""
ri = 1
for day,month in dates:
if len(matches) is 0:
return schedule
print('Generating day {:d}: {:d}/{:d} [remaining:{:d}]'.format(ri, day, month, len(matches)))
ri += 1
busyteams = []
# Each round should have half the teams amount of matches
toschedule = hteams
if len(matches) < toschedule:
# Schedule remaining matches
toschedule = len(matches)
for match in range(toschedule):
(home,road) = matches.pop(0)
# Avoid scheduling same team twice the same date
# This is lazy, but seems to work ok...
# Constraint programming much better but not worth the effort
ok = False
if home in busyteams or road in busyteams:
# Try teams x 2 times, then givup and continue with next date
for i in range(teams * 2):
if home in busyteams or road in busyteams:
matches.append((home,road))
(home,road) = matches.pop(0)
else:
ok = True
break
else:
ok = True
if not ok:
# Don't forget any matches...
matches.append((home,road))
continue
busyteams.append(home)
busyteams.append(road)
for division in range(divisions):
offset = division * 100
divhome = offset + home
divroad = offset + road
schedule += '{:d},{:d},{:d},{:d},{:d}\n'.format(divroad, divhome, day, month, year)
# This should be zero, otherwise tweak script or run again
print('Remaining matches to be scheduled: {:d}'.format(len(matches)))
return schedule
# Header
sl = open('schedule_list_he.csv', 'w')
sl.write('schedule_list,,,,\n')
sl.write('Road Team ID,Home Team ID,Day of Month,Month,Year Offset\n')
# Hard-coded dates day, month
