The normals can be precomputed and stored for each vertex of the model. Alternatively, all the possible solutions can be precomputed and stored in a table. The table is 256 bytes of precomputed 8-bit square root values. Output is typically stored in a read-only database, with updates completely replacing existing precomputed views. Using this precomputed data many queries can be answered taking very little time (microseconds) each. Systems using the MAVLink protocol can use a precomputed array to this purpose. Gbrowse and precomputed files are for genome-wide analysis, bioinformatics, and comparative genomics. So that is 2*N distinct precomputed values, hence LCP-LR is O(N) in size. The running time is a constant factor if the paths are precomputed. The M-tree also keeps the distances from the parent node precomputed to speed up queries. Precomputed values for codice 15 are simply looked-up whenever needed.
