Steps to Fleury's Algorithm. Step 1. Select any vertex to start with. Step 2. Traverse any available edge starting with this vertex. Only traverse a bridge if there is no alternative edge to select. Step 3. Repeat step 2 until there are no more edges left. The resulting trail will be an Eulerian trail (given an Eulerian graph).Eulerian Circuit is an Eulerian Path which starts and ends on the same vertex. A graph is said to be eulerian if it has a eulerian cycle. We have discussed eulerian circuit for an undirected graph. In this post, the same is discussed for a directed graph.

Looks like Eulerian trai (rather than circuit) is the term I am looking for.The idea behind Fleury’s algorithm can be paraphrased by that old piece of folk wisdom: Don’t burn your bridges behind you. Fleury’s Algorithm In graph theory the word bridge has a very specific meaning–it is the only edge connecting two separate sections (call them Fleury’s Algorithm A and B) of a graph, as illustrated in Fig. 5-18.

In addition, an improved Fleury algorithm was proposed to solve Eulerian circuit and plan an optimal running route for robot inspection. To accurately identify weld lines, deep learning networks were constructed and trained with weld line data sets, which were captured by the camera mounted in the front of the robot.
