For the rest of this article, imagine a hashmap with the collision problem resolved. The aim of this article is to provide the time complexity of the coding for insertion into a hashmap, coding for deletion into a hashmap, and coding for searching in a hashmap. The time complexity for ...

(1) complexity reduction – my code usually find the 1st and 2nd solution within half hour, using about 4G memory. (2) extra flexibility – it is possible to use different methods for different sub-regions, or using different strategies to connect solutions from subregions. since it is a ty...
(Small Fitch Parsimony Problem) Given an unrooted binary treeTand an unordered binary characterc, both on species setS, theFitch parsimony score, denotedFitch(T,c), is the minimum number of substitutions needed to explain the evolution ofconT. AFitch-labelingfor (T,c) is a function\({\hat...
In (2), the Chronos speech event is temporally ordered relative to the Utterance Time (UT) by the past tense in the RC, but remains unordered relative to the matrix past meeting event: the past speech event can either be backward-shifted ((3a)) or forward-shifted ((3b)) with regard ...
