WebOverall, our decoding algorithm has two hyper-parameters: the match length n and the copy length k, which control how aggressively we trigger and apply the copy mechanism. 2.3 Application Scenarios Our decoding algorithm can be beneﬁcially applied to any scenarios where the generation outputs have signiﬁcant overlaps with reference documents. • The activity selection problem is characteristic of this class of problems, where the goal is to pick the maximum number of activities that do not clash with each other. • In the Macintosh computer game Crystal Quest the objective is to collect crystals, in a fashion similar to the travelling salesman problem. The game has a demo mode, where the game uses a greedy algorithm to go to every crystal. The artificial intelligence does not account for obstacles, so the demo mode often ends q… WebIn mathematics, economics, and computer science, the stable marriage problem (also stable matching problem or SMP) is the problem of finding a stable matching between two equally sized sets of elements given an ordering of preferences for each element.

WebGreedy matching, on the other hand, is a linear matching algorithm: when a match between a treatment and control is created, the control subject is removed from any further consideration for matching. When the number of matches per treatment is greater than one (i.e., 1:k matching), the greedy algorithm finds the Webthe competitive ratio of fractional (and hence randomized) online matching algorithms can be bounded below by 4/3, by an easy analysis of the same set of input sequences that …
