WebFeb 19, 2016 · Strassen's algorithm is a rather complicated divide-and-conquer algorithm, so the number of operations will involve the logarithm of n. If you want to cheat a bit, you can look at the Wolfram MathWorld entry on Strassen's Formula, which contains a bit of explanation (and the correct number -- you're off by a factor of about 4). – Christian Clason In linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm for matrix multiplication. It is faster than the standard matrix multiplication algorithm for large matrices, with a better asymptotic complexity, although the naive algorithm is often better for smaller matrices. The Strassen algorithm is slower than the fastest known algorithms for extremely large matrices, but such galactic algorithms are not useful in practice, as they are much slower for matrices of pr… how do the amish bury their dead
