Sure thing, let’s treat the PCB like a city map. Think of each pad as a node and each possible wire as an edge weighted by length. A shortest‑path algorithm, like Dijkstra, can find the minimal route between two components. If you’re connecting multiple points, that’s a traveling salesman problem—use a heuristic like nearest neighbor or a genetic algorithm to keep the total wire short while staying in the allowed layers. Remember to avoid crossing edges that aren’t allowed—plan a planar embedding first, then add vias only where needed. Need a quick sketch of the graph layout? Just give me the component list, and I’ll whip up a draft.
