An optimality index for choosing the shortest route in an acyclic, stochastic network has recently been proposed. The present note identifies certain anomalies in using that index and proposes another ...

Combinatorial optimization problems are problems that arise in everyday situations, involving the puzzle of determining the shortest route that can be taken between multiple points. Researchers have ...

Bumblebees can find the solution to a complex mathematical problem which keeps computers busy for days. Scientists in the UK have discovered that bees learn to fly the shortest possible route between ...
