Contraction hierarchies - Wikipedia

The contraction hierarchies (CH) algorithm is a two-phase approach to the shortest path problem consisting of a preprocessing phase and a query phase. As road networks change rather infrequently, more time (seconds to hours) can be used to once precompute some calculations before queries are to be answered. Using this precomputed data, many queries can be answered takin… Web作者：Zhang Qing-ZheCorresponding author Key Laboratory for Highway Construction Technique and Equipment of Ministry of Education of China Chang’an University Xi’an 710064EmailOther articles ... 机译：确定可靠性指标的算法 ...
