WebJul 30, 2024 · Trie is one of the most common data structures for string storage and retrieval. As a fast and efficient implementation of trie, double array (DA) can effectively compress strings to reduce storage spaces. However, this method suffers from the problem of low index construction efficiency. To address this problem, we design a two-level … WebThe item Ordered structures and partitions, by Richard P.

WebDec 21, 2024 · The ( P, w) -partition generating function K ( P, w) ( x) is then defined as K ( P, w) ( x) = ∑ f ∈ ( P, w) -partition ∏ y ∈ P x f ( y). When the labeling w is order-preserving, we simply write K P ( x), as this function is then independent of the choice of labeling. See also enriched P-partitions, where peaks are used instead of descents. WebMay 29, 2024 · It is shown that this partial order is strictly antitone to the number of downsets of so called simple extensions; additionally the downset number of a simple extension is the maximum of the downset numbers of all extensions having the same type as the simple extension.
