_{What is euler's circuit. But for the sake of the principle, what you are trying to implement is that euler_rec (x0,y0,h,x) returns the solution approximation at time x for initial point (x0,y0). Thus the recursive call should be. yprev = euler_rec (x0,y0,h,x-h); y = yprev + h*f (x-h,yprev); and around that you have to construct the body of the recursion function. }

Euler's great innovation was in viewing the Königsberg bridge problem abstractly, by using lines and letters to represent the larger situation of landmasses and bridges. He used capital letters to represent landmasses, and lowercase letters to represent bridges. This was a completely new type of thinking for the time, and in his paper, Euler ...The Euler circuit number k(S) of a pairing S. The Euler circuit number, or just circuit number k(S) of a pairing is defined to be the number of Euler circuits in its 2-in, 2-out graph; equivalently it is the number of Euler paths ending with a distinguished edge, such as the edge e 2n.An Euler path, in a graph or multigraph, is a walk through the graph which uses every edge exactly once.

In the first section, we created a graph of the Königsberg bridges and asked whether it was possible to walk across every bridge once. Because Euler first studied this question, these types of paths are named after him. This link (which you have linked in the comment to the question) states that having Euler path and circuit are mutually exclusive. The definition of Euler path in the link is, however, wrong - the definition of Euler path is that it's a trail, not a path, which visits every edge exactly once.And in the definition of trail, we allow the vertices to repeat, so, in fact, every Euler circuit is ...Euler circuit is a euler path that returns to it starting point after covering all edges. While hamilton path is a graph that covers all vertex(NOTE) exactly once. When this path returns to its starting point than this path is called hamilton circuit.satisfies the conditions required for an Euler circuit, the question arises of which Euler circuit is "best" - there was a lot of choice in the construction outlined above. The best type of tour from a practical standpoint is a circuit with the fewest turns, especially U-turns or left turns which take extra time and tie up traffic.The Euler's Method is a straightforward numerical technique that approximates the solution of ordinary differential equations (ODE).
