It's 9 years later and Google still doesn't give much info on the constant under the big O.

File: /home/bq60o9f5vzd9/public_html/wikizero.com/application/controllers/Main.php I am doing work which requires as fast matrix multiplication as possible and just want to double-check with this community that the Winograd variant of Strassen's MM algorithm is the fastest practical (so no Coppersmith-Winograd) algorithm. Similar to [10], our proofs apply to any starting algorithm that satisfies a simple uniformity requirement which we formalize later.

As far as I know, the reason that people believe that we can achieve close to O(n^2) is basically by analogy with integer multiplication, so if you want some grasp on the constants it might be worthwhile to look at the constants in FFT multiplication.Incidentally, has the appropriate volume of Art of Computer Programming been released, or will it be soon?

Is the Coppersmith-Winograd algorithm similar to the Strassen algorithm ? File: /home/bq60o9f5vzd9/public_html/wikizero.com/application/views/page/index.php Coppersmith-Winograd algorithm - O().

Show Hide all comments. Coppersmith-Winograd algorithm. It only takes a minute to sign up.I've only ever heard it described as "huge", and a google search turned up nothing.Also, given that the Strassen algorithm has a significantly greater constant than Gaussian Elimination, and that Coppersmith-Winograd is greater still, are there any indications of what constant an O(n^2) matrix multiplication algorithm might have?In your second question, I think you mean "naive matrix multiplication", not "Gaussian elimination".In answer to the second part of your question, I think the conventional wisdom is that there What's the implied constant there?
