Talk:Weissman score

Damn

Rationale & criticism
Why was the formula built this way ?

Factoring in compression time obviously makes sense for any pragmatic purpose, but the rest...
 * 1) The log seems to be to keep the figures at bay, since compression times vary wildly. But shouldn't it happen after the time ratio ? Before is responsible for time unit changing the result. Shouldn't it happen after the size ratio too ? Before means a compressor reaching half the size in twice the time gets a lower score.
 * 2) Does a ratio of compression ratios make sense ? Isn't that the same as (reference compressed size / benchmarked compressed size) ?
 * 3) Why include a scaling in the formula ? Moreover an undefined one ?

All these make the scores less comparable between runs. All things considered, this formula looks like a botched job.--Musaran (talk) 11:58, 1 January 2020 (UTC)


 * We'd need an interview for a citation, but I'd bet the answer to all of these is "it was made for TV".
 * It should be pretty obvious though that the "perfect" algorithm according to this score is just "return the input as-is, then wait for 1 {time unit}". You'll always end up with infinite score compared to any other algorithm. 96.87.87.25 (talk) 18:29, 8 October 2020 (UTC)
