neerajmehrotra - 2010-11-18 9:39 PMThe rating is calculated based on a scientific algorithm (and very difficult to explain here), which uses multiple factors (e.g. scores, consistency, # of tests). The maximum possible rating is 1000 and the minimum is 0.Best way to come up in the ratings is to keep on playing regularly (dont miss the tests) and try and do well........

It would be nice if you add points change (for ex. +16) in comparison with score from previous leaderboard.And similar statistic for player position change :)

Just a proposition for the rating:
It would be interesting to indicate (perhaps with arrows next to the ranking) if the rank of a player is better, worse or equal compared to last ranking (ranking before last test).

Wasn't exactly aware there was a rating system. Guess doing a 100 min. test in 50 minutes isn't exactly good for that.

At least I should be able to go up with the next test?

it was a pleasant surprise to see my ratings increase by 160 points. wasnt actually expecting it to improve as much as it did. i guess 360 points is not bad for someone with just two monthly tests under his belt.

DreamRose311 - 2010-10-21 1:41 AMNow that there have been 5 puzzle tests, can we expect a similar LMI Puzzle Ratings soon?

rakesh_rai - 2010-11-19 9:19 AMBoth are valid points. This is very much a part of the plans, and you'll see this happen sooner than later.

You can check out the LMI Sudoku Ratings page now. Arrows are now included to indicate the change in rank (from previous rating list). The exact changes in the ranks and ratings are explicitly indicated as well.

debmohanty - 2010-11-26 2:47 PM
May be an explanation of what the arrows indicate? It looks like a jump of 10+ ranks is indicated by Up arrow.

You are right. The arrows are largely self explanatory. As of now, we have used five arrows in three colours to indicate the changes in ranks, as below:

- The green arrow indicates that the player is on the up, and has made major gains (10+) in the ranks as compared to last ranking list.
- This arrow indicates that the player has made minor gains in ranks (1-9).
- The right blue arrows indicate that there is no change in the rank.
- This arrow indiates that the player has dropped 1-9 ranks.
- The red arrow indicates that the player has dropped 10+ ranks.

Thanks for explaining.
So there is no 'major' jump (in either direction) in top20.
But I would think that cpickerel and willwc cases are significant jumps.
The point i'm trying to make is a jump of 5 ranks in top20 or jump of 10 ranks in top50 or a jump of 20 ranks in top100 should be considered as major.

Jump or Drop you mean :)

rakesh_rai - 2010-11-26 4:28 PM
I think you meant a drop for cpickerel. Thanks Rishi.

debmohanty - 2010-11-26 4:32 PM



Yes - I used jump for both the directions. drop is the correct word.

DreamRose311 - 2010-12-17 8:56 PM

The rating system is really cool, thanks for doing this. One issue though, on both 'change' columns, when you sort by that column, it doesn't quite sort correctly. For instance all numbers starting with 1, whether it's 1 digit, 2 digits, or 3 digits are all grouped together. (it sorta goes 1, 10, 100, 11, 110, 111)...

debmohanty - 2010-12-28 12:37 PMThe sorting works the way it does because of the square brackets around the numbers.Rakesh, any reason why the numbers have to be bracketed?
