Description of fast matrix multiplication algorithm: ⟨2×11×18:306⟩

Algorithm type

2 X Y^{8} Z + 3 X Y^{7} Z + 10 X Y^{6} Z + 7 X^{2} Y^{3} Z^{2} + 13 X Y^{5} Z + 83 X^{2} Y^{2} Z^{2} + 8 X Y^{4} Z + 21 X Y^{2} Z + 159 X Y Z

Algorithm definition

The algorithm ⟨2×11×18:306⟩ is taken from:

John Edward Hopcroft and Leslie R. Kerr. On minimizing the number of multiplication necessary for matrix multiplication. SIAM Journal on Applied Mathematics, 20(1), January 1971. [DOI]

Algorithm description

maple tensor representation (compressed by bzip2);
maple LRP representation (compressed by bzip2);
maple evaluation scheme (compressed by bzip2).

These encodings are given in compressed text format using the maple computer algebra system. In each cases, the last line could be understood as a description of the encoding with respect to classical matrix multiplication algorithm. As these outputs are structured, one can construct easily a parser to its favorite format using the maple documentation without this software.
