Discrete combinatorial optimization has a central role in many scientific disciplines, however, for hard problems we lack linear time algorithms that would allow us to solve very large instances.

A formula for solving combinatorial problems such as finding the most efficient airline or delivery route as well as solving crossword puzzles, Sudoku and similar games. The backtracking process ...

A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study ...
