How do FIDE rated players perform on lichess?

Are chess players getting better, given the same rating?

Would an ensemble of chess engines beat the best one?

In many areas such as prediction and classification, ensemble methods tend to outperform individual methods. This made me wonder if it would make sense to pick a few of the top chess engines and work with them together to make a stronger one. Let us…

Are Elo ratings adjusted after each match, or after each tournament?

I'm aware that the FIDE ratings list is only published once per month. I'm interested in how often the ratings are recalculated internally to FIDE without being published. Are ratings adjusted match after match, or after every tournament? Even if…

Is there any software (or web-based service) that allows you to keep track of local, club-level Elo ratings? These ratings would not have any connection with official Elo ratings, it would be just an Elo rating within the universe of players in a…

Does the average elo of a group that plays only amongst themselves stay constant? For example, say 100 players start with 2000 rating and they play only amongst themselves many times. Will their total ELO remain at 2000*100, decay, or increase over…

Why have engines not increased top rated chess players' Elo?

The arrival of strong chess engines as Stockfish, Houdini or Rybka allow top players to deeply prepare lines in openings or to study better endgames. I would expect a rating increase of top players. However, Kasparov's top score from 1999 is still…
