Atgeir Atgeir An atgeir, sometimes called a "mail-piercer" or "hewing-spear," was a type of polearm in use in Viking Age Scandinavia and Norse colonies in the British Isles and Iceland. It is usually translated in English as "halberd", but most likely closer resembled a bill or glaive during the Viking age. Another view is that the term had no association with a specific weapon until it is used as an anachronism in saga literature to lend weight to accounts of special weapons. Later the word was used for typical European halberds, and even later multipurpose staves with spearheads were called "atgeirsstafir".
Library of Efficient Data types and Algorithms graph algorithms are also available for Java development environment. Library of Efficient Data types and Algorithms The Library of Efficient Data types and Algorithms (LEDA) is a proprietarily-licensed software library providing C++ implementations of a broad variety of algorithms for graph theory and computational geometry. It was originally developed by the Max Planck Institute for Informatics Saarbrücken. Since 2001, LEDA is further developed and distributed by the Algorithmic Solutions Software GmbH. LEDA is available as Free, Research, and Professional edition. The Free edition is freeware, with source code access available for purchase. The Research and Professional editions require payment of
