Pollaxe Pollaxe The pollaxe is a type of European polearm. It was widely used by medieval infantry. It is also known by the names poleaxe, pole-axe, pole axe, polax, and Hache (French meaning axe).

Weapons such as the halberd, bardiche, and Danish axe are sometimes mistakenly called pollaxes as they are indeed axes mounted on poles, but many etymological authorities consider the "poll"- prefix historically unrelated to "pole", instead meaning "head". However, some etymologists, including Eric Partridge, believe that the word is derived from "pole". The
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
