Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...

In a reexamination of existing combinatorial optimization (graph) algorithms used to find the best solution with minimum enumeration, scientists from Simula Research Laboratory (Norway), University of ...
