The city cantons could also employ siege engines . Berne in the Burgdorferkrieg of 1383-84 used medieval types of catapults and battering rams, but for the first time also cannons
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
