precomputation

precomputation

[¦prē‚käm·pyə′tā·shən]
(navigation)
The process of making navigational solutions in advance, applied particularly to the determination of computed altitude and azimuth before making a celestial observation for a line of position; when this is done, the observation must be made at the time used for the computation, or a correction applied.

Notably, optimization techniques are used to make the whole trajectory-planning process very efficient, with the precomputation taking little more than 100 milliseconds to find and refine safe paths.
Their scheme provides provable security in the standard model and achieves a low computational cost by implementing a precomputation technique.
Another example, where both power and area estimates are relevant, is the evaluation of power optimization methods, such as clock gating, precomputation and partitioning [12]; these methods come with a circuit overhead, thus in early design stages the designer must have an information about the power saving potential vs.
This stage consists of three phases: the offline phase, the precomputation phase, and the rendering phase.

Contraction hierarchies (CH) is also a time-dependent technique that performs precomputation for node contraction [4].
In [41], the computational demands with RW are alleviated by introducing an "offline" precomputation before user interaction with RW in real-time "online." Using a similar principle, an offline precomputation was used to further speed up the online segmentation in [42].
Note that we neglect the precomputation of the necessary matrices ,[mathematical expression not reproducible], and [mathematical expression not reproducible].
Given that my colleagues and I worked on this problem for multiple years, which is not uncommon in industry, it was entirely acceptable to design and implement a domain-specific planner that uses fast C-implementations for required set operations, the z-buffer algorithm (Rossignac and Requicha 1986) for geometric reasoning, and intelligent precomputation of action effects where possible.
