I feel like this would be a low priority, but would it be possible to eventually implement by-event statistics? By that I mean... say you click on an event, like http://aligulac.com/results/events/449-Proleague/ , then at the top there is a collapsible stats panel which has things like TvP/PvZ/ZvT scores, number of games/players total, etc. Much like TLPD.

Your wish is my command!

Example: http://aligulac.com/results/events/36-GSL-2013-Season-1/

I couldn't get you the player count because the query was waaaay to slow. Need to do some database optimization first. TT

Also, I opened a ticket list: https://github.com/TheBB/aligulac/issues

If you want you can just dump your feature requests and bugs there, too.

Just curious...how are you going to handle HOTS? WoL data won't be too relevant...will it be a clean slate? will there be a formula that gives notion to the WoL stats? Will it just be added to the WoL data?

Currently we are adding matches from both games, yet we have an indicator on each match whether it is WoL or HotS.

I believe currently the rankings contain both, and the plan is to just let it transition with the launch of HotS.

Ah I didn't realize the source code was on github, cool!

About the fake games, could you add a fraction instead of a full win and full lose? Just adding 0.1 Loss and 0.1 Win or something like to prevent infinity problems. Otherwise it seems like it would slow down rating movement more than it should, especially of players that go 1-0 many periods in a row. Or wouldn't it be better to just maximize the new rating all at once -- maximize log likelyhood given period game results *and* prior myr/mys value? Instead it looks like you first maximize this period performance, and then as a second step combine with prior myr/mys to come up with a new rating.

Another problem with adding fake games is doesn't that cause the confidence in the rating to go up 3X as fast in the case of players going 1-0 or 0-1 every period? This makes the problem of those players' rating getting stuck worse too.

Also, where can I find these values?
from aligulac.settings import RATINGS_MIN_DEV, RATINGS_INIT_DEV

ETA: Also maybe you could just keep the fake games even when players do not go 0-N/N-0. Otherwise it seems to me that there are weird cases where going 3-1 against a stronger opponent could make your rating move more than going 3-0.

Hey KillerDucky, you seem to know what you're talking about.

«Fake» games: Yeah, it's possible that a different value than 1-1 could help. I know that it can slow down rating change, but I didn't consider that it can decrease the RD too. I'll think about it. Of course I could also maximize the whole thing in one go. I did it this way since I was following Glickman's algorithm and I never thought to change it. I'm not exactly sure it it would have any strange effects.

The settings file is kept from the repo because it contains some passwords. (I didn't bother filtering those out.) The constants you need are:

RATINGS_INIT_DEV = 0.12
RATINGS_MIN_DEV = 0.02
RATINGS_DEV_DECAY = 0.008

Is there a way with Aligulac to plot the rating of say the 50 best players over the last two years all at once ?

For a while it was possible with the site mengsk.com (unfortunately the site is now dead). You would have all the graph of all the players superimposed and selecting a particular player would highlight his curve. It was quite fascinating to see the progression of a player ELO along the years.

For an illustration, the graphs from mengsk.com have been used in this TL article (comparing broodwar and chess)

Not currently possible. But in theory yes that should be doable, since the system already supports graphs, just not implemented.

Edit: This is not me saying that this is something being considered, just that it should be possible.

If you want players to be highlightable I guess I have to use Javascript. Does anyone know of a graph widget like that?

Highcharts is a very powerful Javascript graphing library. It has highlighting/hover ability. I use it extensively at GGTracker and I'd be happy to answer questions about it if anyone gets stuck with a Highcharts problem.

Just noticed that in IPL TAC 3, Losers' Bracket Round 5 StarTale vs Prime, Byun is listed as beating Bomber.

http://aligulac.com/results/search/?op=search&after=&before=&players=Bomber
Byun&eventtext=IPL TAC

However, Bomber actually beat Byun.

Noticed something strange:

http://aligulac.com/players/7-Rain/period/79/

Rain is 1-0 vZ this period so far, but his vZ rating went down 3 points. Bug maybe?

Maybe aligulac thinks Zenio is so bad that Rain would need to beat him 2-0 in a Bo1 in order to maintain his rating, I don't know.

Go Switzerland! I would love to visit that country one more time, but my parents are wanted criminals there, so... :D

The ratings don't change independently. His other performances are dragging him down. The interpretation should be that yeah, he beat Zenio, but he has performed so poorly otherwise that it's reasonable to believe that his strength versus Zerg actually isn't any higher.
