WebApr 29, 2024 · However, in Boolean matrix multiplication the addition of elements is the Boolean disjunction: 1 + 1 = 1 instead of zero. This innocent change means that subtraction no longer works: from x + 1 = 1 you cannot know whether x = 0 or x = 1. Thus Strassen's algorithm, unmodified, does not work with Booleans. WebFeb 3, 2024 · One step of AES requires the following operation: $$e_ {i,j} = m_ {i,j} * c_ {i,j} \oplus k_ {i,j}$$. where $e_ {i,j}, m_ {i,j}, c_ {i,j}, and \space k_ {i,j}$ are all $4 \times 4$ …
WebJan 1, 2016 · The time complexity of Boolean matrix multiplication can be improved to \(\tilde{O}(n^{2.5})\) by observing that the inner product of two Boolean vectors of length n can be computed with \(O(\sqrt{n})\) queries using Grover’s algorithm . This observation also speeds up matrix multiplication over some other semirings. WebMay 5, 2016 · We consider the Online Boolean Matrix-Vector Multiplication (OMV) problem studied by Henzinger et al. [STOC'15]: given an Boolean matrix , we receive Boolean vectors one at a time, and are required to output (over the Boolean semiring) before seeing the vector , for all .
WebWe use randomness to exploit the potential sparsity of the Boolean matrix product in order to speed up the computation of the product. Our new fast output-sensitive algorithm for Boolean matrix product and its witnesses is randomized and provides the Boolean product and its witnesses almost certainly.
