Re: Differential Directory, indexing method 9 Hours Ago by xrjf I've just made an update because some records weren't being added properly. The issue was that the form didn't take into account that the register field (in the call to DiDi) is passed by reference. Differential Directory, indexing method 4 Days Ago by xrjf … this position in the index. * With at most one single disk read, assuming the index is in memory, it determines whether… left and right nodes (if they exist), and to the disk record where the full key and its data are stored…, and only a maximum of 3 nodes and a single disk read are required per insertion. Re: Differential Directory, indexing method 4 Days Ago by rproffitt DiDi appears to be some China based UBER service but then again I can't find a question or much else to discuss here. Re: Differential Directory, indexing method 3 Days Ago by xrjf About DiDi DiDi (Differential Directory) was originally developed as part of my thesis project in the early 1990s. The name bears no relation to the more recent Chinese ride-sharing company. At the time, DiDi was a novel approach within its academic context, but a change in legislation unfortunately led to the closure of the school and the … Re: Differential Directory, indexing method 3 Days Ago by xrjf For example, as Donald Knuth points out in The Art of Computer Programming, the theoretical lower bound for comparison-based sorting algorithms is K × log₂(N). I developed a very simple method that matches this performance. However, DiDi goes far beyond: its performance is proportional to K × (maximum key length), regardless of the number of … Re: Differential Directory, indexing method 3 Days Ago by xrjf As an illustration, consider the theoretical lower bound for comparison-based sorting, as stated by Donald Knuth in The Art of Computer Programming: K × log₂(N). I developed a simple method that matches this limit. For example, to sort the list {2, 5, 7, 1, 4, 3, 8, 6}: Sort pairs: (2, 5) → [1] (1, 7) → [2] (3, 4) → [3] (6, 8) → [4] Merge… Re: Differential Directory, indexing method 3 Days Ago by xrjf "Just to clarify a previous mistake: the efficiency should be K × N × log₂(N), not K × log₂(N) as I initially wrote."
