WebTechnique 2: Strassen’s Algorithm. In this method, we use the algorithm given by Strassen. The advantage of this algorithm is, that it uses less number of operations then the naive method. It uses divide and conquer strategy, and thus, divides the square matrix of size n to n/2. It reduces the 8 recursive calls to 7. WebImplementing the Algorithm. If you are looking for implementing the algorithm, the main challenges would be in partitioning a matrix in quadrants, especially when the dimensions are not divisible by 2, i.e. initial matrix dimensions are not power of 2. Also recombining the partitioned quadrant will need some thoughts. You can find thorough and ... inamovible antonyme

WebWe now need to figure out when Strassen begins to have a lower cost than the normal matrix multiplication algorithm. To find this we can look at the crossover point where Strassen switches to regular matrix multiplication. We need to look at: 2n^3 − n^2 = 7(2(n/2)^3 − (n/2)^2) + 18(n/2)^2. This gives us n0 = 15, or cp = 15. WebStrassen Algorithm Implementation of the Strassen Algorithm in C The Strassen algorithm, is an algorithm for matrix multiplication.
