51P (complexity) — In computational complexity theory, P, also known as PTIME or DTIME(nO(1)), is one of the most fundamental complexity classes. It contains all decision problems which can be solved by a deterministic Turing machine using a polynomial amount of… …
52Cluster analysis — The result of a cluster analysis shown as the coloring of the squares into three clusters. Cluster analysis or clustering is the task of assigning a set of objects into groups (called clusters) so that the objects in the same cluster are more… …
53Exterior Gateway Protocol — The Exterior Gateway Protocol (EGP) is a now obsolete routing protocol for the Internet originally specified in 1982 by Eric C. Rosen of Bolt, Beranek and Newman, and David L. Mills. It was first described in RFC 827 and formally specified in RFC …
54VoIP spam — VoIP spam, is the proliferation of unwanted, automatically dialed, pre recorded phone calls using Voice over Internet Protocol (VoIP). Some pundits have taken to referring to it as SPIT (for Spam over Internet Telephony ).Voice over IP systems,… …
55Rabbit Model Checker — Rabbit is a model checking tool for real time systems. The modeling language are timed automata extended with concepts for modular modeling. The tool provides reachability analysis and refinement checking, both implemented using the data… …
56Customised Applications for Mobile networks Enhanced Logic — Customised Applications for Mobile networks Enhanced Logic, or CAMEL (ETSI TS 123 078) for short, is a set of standards designed to work on either a GSM core network or UMTS network. They allow an operator to define services over and above… …
57Database theory — encapsulates a broad range of topics related to the study and research of the theoretical realm of databases and database management systems. Theoretical aspects of data management include, among other areas, the foundations of query languages,… …
58List of NP-complete problems — Here are some of the more commonly known problems that are NP complete when expressed as decision problems. This list is in no way comprehensive (there are more than 3000 known NP complete problems). Most of the problems in this list are taken… …
59Polytree — A simple polytree In graph theory, a polytree is a directed graph with at most one undirected path between any two vertices. In other words, a polytree is a directed acyclic graph (DAG) for which there are no undirected cycles either.… …
