Pairwise neighbor lists
WebMar 12, 2013 · With a 10000 element long array: In [2]: %timeit nearest_neighbors_sorted (x, y) 1 loops, best of 3: 557 ms per loop In [3]: %timeit nearest_neighbors (x, y) 1 loops, best of 3: 1.53 s per loop. For smaller arrays it performs slightly worse. You are going to have to loop over all your items to implement your greedy nearest neighbor algorithm ... WebMar 3, 2024 · Description. This command sets parameters that affect the building of pairwise neighbor lists. All atom pairs within a neighbor cutoff distance equal to the their force cutoff plus the skin distance are stored in the list. Typically, the larger the skin distance, the less often neighbor lists need to be built, but more pairs must be checked …
