This course covers basics of algorithm design and analysis, as well as algorithms for sorting arrays, data structures such as priority queues, hash functions, and applications such as Bloom filters. Algorithms
Comparing two sorting algorithms(比较两种排序算法)(267) 6. Shellsort(希尔排序)(271) 2. MERGESORT(归并排序)(283) 1. Abstract in-place merge(抽象就地合并)(283) 2. Top-down mergesort(自顶向下合并排序)(285) 1. Use insertion sort for small subarrays(对于小子数组使用插入排序)(288) 2. ...
Indexing involves extracting and analyzing the content and metadata of documents to create an index, which is a data structure optimized for quickly searching and retrieving information. Querying: An information retrieval process starts when a query enters the system. A query is a statement that a ...
bigoref.com uses the term “indexing” where bigocheatsheet.com uses “access”. I’ve stuck with “access” for bigoquiz.com. bigoref.com splits array into Basic Array and Dynamic Array, not allowing insertion or deletion in a Basic Array. I don’t find the distinction useful, so I ...

Spatial indices are a family of algorithms that arrange geometric data for efficient search. For example, doing queries like “return all buildings in this area”, “find 1000 closest gas stations to this point”, and returning results within milliseconds even when searching millions of objects. ...
(to 20 mm) and siftings from crushing and sorting plants is used in wells. Water stemming of well charges is less effective, since its ejection resistance decreases sharply with an increase in diameter. Stemming made with pieces of rock no larger than 300 mm is advisable for case charges....
External sorting algorithms allow for sorting large amounts of data by only considering a small fraction of that data at a time. They are used when the data being sorted do not fit into the main memory of a computing device (e.g. RAM), and instead must reside in the external memory (...
EFGs (Fig.1d) organize multiple sequence alignments (MSAs) as a graph [33,34]. It splits MSAs into blocks, merges identical nodes within the same blocks, and connects the remaining nodes to form a graph. EFG has achieved a breakthrough in indexing labeled graphs by allowing for a polynom...
Maximum parsimony (phylogenetics) : an algorithm for finding the simplest phylogenetic tree to explain a given character matrix. Merge sort : sort the first and second half of the list separately, then merge the sorted lists Metaphone : an algorithm for indexing words by their sound, when pron...
