A graph algorithm could map each fragment’s edges to potential matches, like a network of bone fragments waiting for their counterparts. The trick is to assign weights that reflect morphological fit—surface texture, curvature, and even tiny micro‑striae. Then run a maximum‑weight matching; it’ll pair pieces that best satisfy the fossil’s original geometry. Just remember, no algorithm can replace the tactile insight of a hand that feels the subtle difference between a fossilized mandibular symphysis and a random rock fragment.

That sounds sensible—just keep the weight function precise and tuned to bone morphology. And remember, the manual check is vital; fossils have quirks that algorithms can miss, especially when surface noise hides the real fit.
