Calculating Kolmogorov complexity from the output frequency distributions of small Turing machines. [PDF]

open access: yesPLoS ONE, 2014
Drawing on various notions from theoretical computer science, we present a novel numerical approach, motivated by the notion of algorithmic probability, to the problem of approximating the Kolmogorov-Chaitin complexity of short strings.

The U-curve optimization problem: improvements on the original algorithm and time complexity analysis

open access: yesCoRR, 2014
The U-curve optimization problem is characterized by a decomposable in U-shaped curves cost function over the chains of a Boolean lattice. This problem can be applied to model the classical feature selection problem in Machine Learning. Recently, the U-Curve algorithm was proposed to give optimal solutions to the U-curve problem.

Analysis of solving methods and complexity of algorithmics problems in Lithuanian and Baltic Olympiads

open access: yesLietuvos matematikos rinkinys, 2003
Lithuanian Olympiads in Informatics are being organized since 1990. Each Olympiad consists of three rounds. The final (national) one is divided into two parts, there are also elder and younger divisions. Each year there are supplied a lot of tasks. The paper deals with algorithmic problems of all the Lithuanian olympiads of school students and all the ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...
