This program calculates all possible paths over bridges (or I hope).Two bridges were not restored after WWII and a new bridge replaced two other bridges in 1970's. Plus some other bridges have been built nearby (outside the area delimited by the original seven bridges but within the old "Eulerian" borders of Königsberg). Also, the border of the city has changed since Euler's times. It is obvious that we cannot satisfy both of these conditions at the same time.
