Dominating Set
In graph theory, a dominating set for a graph is a subset of its vertices, such that any vertex of is either in , or has a neighbor in . The domination number is the number of vertices in a smallest dominating set for . The dominating set problem concerns testing whether for a given graph and input ; it is a classical NP-complete decision problem in computational complexity theory. Therefore it is believed that there may be no efficient algorithm that can compute for all graphs . However, there are efficient approximation algorithms, as well as efficient exact algorithms for certain graph classes. Dominating sets are of practical interest in several areas. In wireless networking, dominating sets are used to find efficient routes within ad-hoc mobile networks. They have also been used in document summarization, and in designing secure systems for electrical grids. Formal definition Given an undirected graph , a subset of vertices D\subseteq V is called a dominating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towson University Faculty
Towson () is an unincorporated community and a census-designated place in Baltimore County, Maryland, United States. The population was 55,197 as of the 2010 census. It is the county seat of Baltimore County and the second-most populous unincorporated county seat in the United States (after Ellicott City, the seat of nearby Howard County, southwest of Baltimore). History 1600s The first inhabitants of the future Towson and central Baltimore County region were the Susquehannock people, who hunted in the area. Their region included all of Baltimore County, though their primary settlement was farther northeast along the Susquehanna River. 1700s Towson was settled in 1752 when Pennsylvania brothers, William and Thomas Towson, began farming an area of Sater's Hill, northeast of the present-day York and Joppa Roads. William's son, Ezekiel, opened the Towson Hotel to serve the growing number of farmers bringing their produce and livestock to the port of Baltimore. He built the hote ...

21st-century American Women Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, ...
