Optimizing Implementations of Linear Layers

IACR Transactions on Symmetric Cryptology, 2020
In this paper, we propose a new heuristic algorithm to search efficient implementations (in terms of Xor count) of linear layers used in symmetric-key cryptography. It is observed that the implementation cost of an invertible matrix is related to its matrix decomposition if sequential-Xor (s-Xor) metric is considered, thus reducing the implementation ...

Optimized Linear Imputation

Proceedings of the 6th International Conference on Pattern Recognition Applications and Methods, 2017
Often in real-world datasets, especially in high dimensional data, some feature values are missing. Since most data analysis and statistical methods do not handle gracefully missing values, the first step in the analysis requires the imputation of missing values.

Optimizing Linear Extensions [PDF]

SIAM Journal on Discrete Mathematics, 2009
The minimum number of elements needed for a poset to have exactly n linear extensions is at most 2sqrt{n}. In a special case, the bound can be improved to sqrt{n}.
