<p>The algorithm starts by selecting the leftmost node and proceeds by choosing the topmost segment connected to that node. The process continues by traversing to the next node along the selected segment.</p>
<p>At each node, the algorithm selects the next segment by rotating around the current node in a clockwise/counterclockwise direction for outer/inner co
