A hash family is a collection of N functions from a domain of size k to a range of size w. A function â€˜separatesâ€™ two elements of the domain if it maps them to distinct elements of the range. Aâ€¦ (More)

A covering array CA is a combinatorial structure specified as a matrix of N rows and k columns over an alphabet on v symbols such that for each set of t columns every t-tuple of symbols is covered atâ€¦ (More)

A ternary covering array (CA(N ; t, k, 3)) is an N Ã— k array with entries from the set {0, 1, 2} where every N Ã— t subarray contains each of the 3 combinations at least once. Here, t is called theâ€¦ (More)

Covering Arrays (CAs) are combinatorial objects that, with a small number of cases, cover a certain level of interaction of a set of parameters. CAs have found application in a variety of fieldsâ€¦ (More)

Software test suites based on the concept of interaction testing are very useful for testing software components in an economical way. Test suites of this kind may be created using mathematicalâ€¦ (More)

ARTICLE INFO Covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites f or pairwise testing. While numerous algorithmic techniques haveâ€¦ (More)
