Web12 apr. 2024 · As the frequency variation range of the FA radar is relatively small compared with the nominal frequency f 0, it can be seen from the form of t ˜ m = m T r (1 + c m Δ f / f 0) that the sample points are approximately equispaced, so we adopt a NUFFT algorithm based on low rank approximation.We first introduce the NUFFT algorithm based on low ... Web11 feb. 2009 · The history heuristic is also useful. The top-rated chess program Rybka has apparently abandoned MDT (f) in favour of PVS with a zero-aspiration window on the non-PV nodes. Extended futility pruning, which incorporates both normal futility pruning and deep razoring, is theoretically unsound, but remarkably effective in practice.
