Schedule Match Sequence

[fabiomh]

In order to run some simulations on the new format of next season I need a schedule example for the Champions League, Europa League, and for the Conference League. For CL/EL the schedule of @As_Contas_do_Título (see viewtopic.php?p=486445#p486445) is the best I could find. For the Conference League I use a schedule with strict alternating between home/away matches. Both methods are explained below:

UEFA conditions:
- each club plays an equal number of matches at home and away
- each club plays one home match and one away match on the first two matchdays and the last two matchdays
- no more than two consecutive home or away games in a row

Champions League and Europa League, 36 teams, 4 groups with random labels A-D and random spot 1-9

Format example (similar to method of As_Contas_do_Título):
- split each pot in 3 subgroups i, j, and k based on intra-pot matches
- intra-pot matches played at 3 days of 2nd part of the schedule
- several options to put clubs that cant meet in different (i,j,k) groups

Code: Select all

                                         A A A B B B C C C D D D
                                         i j k i j k i j k i j k

Conference League, 36 teams, 6 groups with random labels A-F and random spot 1-6

Schedule example:
- all intra-pot matches at the same day, and all matches between certain pots at the same day
- home/away strictly alternating for each club
- split each pot in two subgroups i and j based on intra-pot home-away matches
- several options to put clubs that can't meet in different (i,j) groups

Code: Select all

                                         A A B B C C D D E E F F
                                         i j i j i j i j i j i j

Since the schedule is stricly alternating between home and away, matchdays can be cycled up or down to move the intra-pot matches to another day

I like them very much.
Flexible, you can move the intra-pot matches (MDs) in the first half easily.
For 8MDs matches:
- you first draw the teams in 12 sub-pots, based on: a) teams that can't meet; b) team pairings

- intra-pot matches played at 3 days of 2nd part of the schedule

Bart, your analysis is very interesting, but UEFA have promised to make intra-pot A games in every round (marketing purposes). Are you able to make a schedule that fulfills this condition (and some of your other conditions, as you probably can't fulfill all the conditions with intra pot a games every round)?
