as the problem that gave birth to graph
4. Königsberg
Swiss-born mathematician Leonhard Euler (1707-1783). The problem asked
whether one could, in a single stroll, cross all seven bridges of the city of
Königsberg exactly once and return to a starting point. Following is a sketch
of the river with its two islands and seven bridges:
a. State the problem as a graph problem.
b. Does this problem have a solution? If you believe it does, draw such a stroll;
if you believe it does not, explain why and indicate the smallest number of
new bridges that would be required to make such a stroll possible.
5. Icosian Game A century after Euler's discovery (see Problem 4), another
famous puzzle-this one invented by the renowned Irish mathematician Sir
William Hamilton (1805-1865)-was presented to the world under the name
of the Icosian Game. The game's board was a circular wooden board on which
the following graph was carved:
Find a Hamiltonian circuit-a path that visits all the graph's vertices exactly
once before returning to the starting vertex-for this graph.
5. Consider the following problem: Design an algorithm to determine the best
route for a subway passenger to take from one designated station to another in
a well-developed subway system similar to those in such cities as Washington,
D.C., and London, UK.

The following is a graph theory problem: Suppose we have a graph A = (X, Y) and a subgraph of A, which is expressed as B = (x, y). x is an element of X and y is an element of Y.

Be careful when answering the following questions to leave edges that have their endpoints in B.
