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.

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.
