Covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. While numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. Random generation techniques c...

In the past, most software tests were performed using manual methods. This required a large staff of test personnel to perform expensive and time-consuming manual test procedures. Owing to the size and complexity of today’s advanced software applications, manual testing is no longer a viable option for most testing situations. The manual testing approach has inherent risks and costs associated ...

By the very definition of complex systems, complex behaviour emerges from the interactions between the individual parts. This emergent behaviour may be difficult or impossible to predict by analysing the parts. As a result, systematic and thorough testing of the interactions of complex systems, including multi-agent systems, is an important part of the verification and validation process. This ...

This research is concerned with the processes by which individuals use social interaction to actively test hypotheses about other people. In four separate empirical investigations, female participants were provided with hypotheses about the personal attributes of other individuals ("targets"). Participants then prepared to test these hypotheses (i.e., that their targets were extraverts or that ...

Three models of mind-matter interaction (MMI) in random number generators (RNGs) were tested. One model assumes that MMI is a forward-time causal influence, a second assumes that MMI is due to present-time exploitation of precognitive information, and a third assumes that MMI is a retrocausal influence. A pilot test and a planned replication study provided significant evidence for MMI, allowing...
