OsmAnd's HH-Routing is more than just an algorithm; it's a testament to innovative problem-solving. It’s a carefully engineered system born from the need to overcome specific, demanding constraints: the desire for blazing speed, minimal storage, complete routing flexibility, regional map support, and adaptability to fresh data.
Since the initial release, community contributions have pushed data efficiency from ~2.4x to 5.5x against modded-nanogpt, more than doubling in a few days. The key changes are: shuffling at the start of each epoch, which had outsized impact on multi-epoch training; learned projections for value embeddings instead of separate embedding tables; swapping squared ReLU for SwiGLU activation; and ensembling multiple models. 10x data efficiency seems reachable in the short term. 100x might be feasible by the end of the year, given how many directions remain unexplored, but it will require serious exploration on the algorithms side.
