👉 In computer science, a semiperfect graph is a graph that can be drawn without lifting any of its edges to see itself. In other words, it's a graph with no cycles and no odd-length cycles. It's important for algorithms like Dijkstra's algorithm, which use the concept of "shortest path" in graphs, because it guarantees that every vertex will have at most two neighbors, ensuring that there are only one or zero edges between each pair of vertices.
