Street View Imagery of Kaliningrad (Königsberg), Russia Bridge Released

Google has just released a new Google Maps Street View scenery of the historic seaport of Kaliningrad (now called Königsberg), Russia--while using sophisticated algorithms to solve the classic mathematical problem "the Seven Bridges of Königsberg."

The mathematical problem posed an interesting challenge: find a route through Kaliningrad--which was once separated by the Pregel River--by crossing each of the seven bridges in town.

The catch "One could only cross each bridge exactly once."

"In 1735, Leonhard Euler, concluded that there was no solution to the problem because it was impossible to find a route that would cross each bridge only once," Google wrote.
