premii Ad Astra

Asociația Ad Astra a anunțat câștigătorii Premiilor Ad Astra 2022: Proiectul și-a propus identificarea și popularizarea modelelor de succes, a rezultatelor excepționale ale cercetătorilor români din țară și din afara ei.

Asociatia Ad Astra a cercetatorilor romani lanseaza BAZA DE DATE A CERCETATORILOR ROMANI DIN DIASPORA. Scopul acestei baze de date este aceea de a stimula colaborarea dintre cercetatorii romani de peste hotare dar si cu cercetatorii din Romania. Cercetatorii care doresc sa fie nominalizati in aceasta baza de date sunt rugati sa trimita un email la

Mathematicians come up with formula to complete every Sudoku–sort-Mathematicians-come-formula-complete-Sudoku-trying-understand-longer-doing-puzzle.html

For those who enjoy the challenge of a hard Suduko puzzle it could be seen as something of cop-out.

But for those who find them too much of a struggle it could be, literally, just the solution.

Two researchers have developed a mathematical algorithm that solves Sudoku puzzles very quickly, without any guessing or backtracking.

Complex networks researcher Zoltan Toroczkai and Notre Dame postdoctoral researcher Maria Ercsey-Ravasz, from the University of Notre Dame also say they can also explain why some puzzles are harder than others.

Toroczkai and Ercsey-Ravasz, who also studies at Romania’s Babes-Bolyai University, began analysing Sudoku as part of their research into the theory of optimisation and computational complexity.

NOTE: The title (coming from the first quoted press release) is somewhat misleading: Sudoku is a problem that CANNOT be solved efficiently in the general case (it is an NP-complete problem) The algorithm given by Toroczkai and Ercsey-Ravasz does not get around this fundamental limitation, as it comes with no guarantees of efficiency.
