Algorithm: MST-based Approximation
Compute the Minimum Spanning Tree over the complete graph of terminals. The MST provides a 2-approximation to the Steiner tree. For improved results, iteratively find Steiner points that reduce total edge length. O(k² log k) for k terminals.
Why This Matters
Steiner Tree finds optimal networks — roads, circuits, pipelines. The Pluto transformer connects the dots with minimal total length, exactly how the 72-band framework connects frequency nodes.
