Ideally, we would like to run the search with complexity proportional to the number of matches of the least frequent term in the conjunction, which is the standard of plaintext information retrieval algorithms. In addition, the computa- tional efficiency of database processing and of search is ...
These observations imply the following proposition, which helps to better understand the meaning of the main theorems. Proposition 7. Let n ∈ N , and let F be a filter on an infinite set X. (i) Suppose that Y ⊂ B = 2 n ( X ) and U is a neighborhood of zero in the free ...
Currently, many algorithms are available for the point-in-polygon test. Jiménez et al. [1] improved the triangle-based algorithm and did not require any preprocessing, decomposition, or feature classification. However, they are sensitive to whether a polygon is clockwise or counterclockwise oriented...
