For those who struggle to solve a Sudoku puzzle, scientists have come to your rescue!
Researchers at University of Notre Dame have developed a mathematical algorithm that solves Sudoku puzzles very quickly, without any guessing or backtracking.
Researchers, Zoltan Toroczka and Maria Ercsey-Ravasz, however, cannot only explain why some Sudoku puzzles are harder than others. Toroczkai and Ercsey-Ravasz from Romanias Babes-Bolyai University, began studying Sudoku as part of their research into the theory of optimisation and computational complexity.
They note that most Sudoku enthusiasts use what is known as a “brute force” system to solve problems, combined with a good deal of guessing.

‘Fish oils can stave off heart disease risk’
London: Just two or three portions of fish every week or taking an oil supplement can ward off heart disease, especially in women, a new study has claimed.
Researchers from the University of Reading found that fish oils can have a direct impact on the muscle cells that control the elasticity of blood vessels.
Previous studies have shown that the omega-3 fish oils can dramatically cut the risk of death by slashing blood fats, reducing the chance of a blood clot.
The study introduced small amounts of fish oils to meals containing saturated fat eaten by both men and women, the Daily Express reported.
Researchers found that muscle elasticity was improved four-fold in women and two-fold in men. The fish oils were so effective on women they matched the benefits of L-arginine, an amino acid supplement taken for heart health. — PTI
