The scene shows a network of nodes connected by undirected edges (edges without arrows) with a green starting node, a red ending node, and a purple triangular agent positioned at the green starting node. The agent can move along any edge, traversing it from one end to the other in either direction, moving from one node to an adjacent node each step. Move the purple triangular agent from the green starting node to the red ending node along the path with the minimum number of steps.
