A storage and retrieval system utilizing the combinatorial file structure is developed. Storage and retrieval results derived from a simulated document library of 4000 items are presented. ... A file structure designed to provide rapid, random access with minimum storage overhead is presented. ... Although the techniques of randomized file addressing are varied and the associated problems interesting, of principle interest is the application of the randomizing concept to the combinatorial file structure ...doi:10.1145/511285.511304 dblp:conf/sigir/Gustafson71 fatcat:bxos7py6wrfwfdiay23ddc37c4

It can be used in order to produce graphical output for Gala, an uniform random generator of combinatorial structures. ... The program is based on a generic description of the structures, and thus allows to draw structures of an infinite number of classes. ... The Unix command Adocs descr produces the descr.ps Postscript file containing the drawing of the structure. ...doi:10.1007/bfb0021787 fatcat:5cm7fvfanree7l4pombs2ixtda
The generation relies on powerful combinatorial methods together with numerical and symbolic resolution of polynomial systems. ... In this article we present the prototype of a framework capable of producing, with linear complexity, uniformly random XML documents with respect to a given RELAX NG grammar. ...

The results show that compared with conventional random testing, the proposed approach can detect more errors with the same amount of test cases which turning out to be more ideal than existing ones in ... combinatorial testing is proposed to generate variable strength combinatorial test suite based on One-test-at-a-time strategy. ... Schroeder  demonstrated that the error detection ability of N-dimensional combinatorial testing is much higher than the same size of random testing. ...doi:10.20532/cit.2016.1002727 fatcat:wdvi7pge4bcxpmc2u5gxab3e6y
The effectiveness of combinatorial testing is measured in terms of the number of faulty versions that are detected. ... The experimental results show that combinatorial testing is effective in terms of detecting most of the faulty versions with a small number of tests. ... The random test suite and its corresponding combinatorial test set have the same number of tests. ...doi:10.1109/icstw.2013.47 dblp:conf/icst/GhandehariBLKK13 fatcat:6sq43grhb5af5mumk7fmkt5vz4
