[sympy] negative-weight single source shortest paths in near-linear time

2023-01-19 Thread Chris Smith
Just read about https://arxiv.org/abs/2203.03456 in Quanta artical https://www.quantamagazine.org/finally-a-fast-algorithm-for-shortest-paths-on-negative-graphs-20230118/. One of the algorithms used in the solution computes a low-diameter decomposition of the graph, identifying groups of nodes

> Put another way, what would be your preferred computer language if you were SymPy starting again? There would obviously need to be an interface to Python, but would you write the rest in C++? I've studied "Typescript" briefly, because lots of symbolic math are practical due to frontend interfac
