Automatic table layout is required in web applications. Unfortunately, this is NP-hard for reasonable layout requirements such as minimizing table height for a given width. One ap...
Systems of language equations of the form {ϕ(X1, . . . , Xn) = ∅, ψ(X1, . . . , Xn) = ∅} are studied, where ϕ, ψ may contain set-theoretic operations and concatenation; the...
We consider the exact and approximate computational complexity of the multivariate LMS linear regression estimator. The LMS estimator is among the most widely used robust linear s...
The Genome Halving Problem is motivated by the whole genome duplication events in molecular evolution that double the gene content of a genome and result in a perfect duplicated ge...
