Goldberg's Network Optimization Codes Goldberg's Network Optimization Codes The highest performance codes available for such network optimization problems as matching, shortest paths, and network flow have been developed by Andrew Goldberg and his collaborators. All are written in C. Their codes are available by ftp for non-commercial use, although a license is required for commercial use. For information on obtaining the codes, check out Andrew Goldberg's WWW page, http://www.neci.nj.nec.com/homepages/avg.html Their implementations of both Dijkstra and Bellman-Ford's algorithms for finding shortest paths in graphs is SPLIB, developed by Cherkassky, Goldberg, and Radzik. They report solving instances with over one million vertices in under two minutes on a Sun Sparc-10 workstation. Their code for finding a maximum cardinality bipartite matching of maximum weight shortest paths in graphs is CSA, developed by Goldberg and Kennedy. This code is based on a cost-scaling network flow algorithms. Their running times depend upon the density of the networks and weight distributions, but they report solving instances with over 30,000 vertices in a few minutes on a Sun Sparc-2 workstation. Their code for solving maximum-flow in graphs is PRF, developed by Cherkassky and Goldberg. They report solving instances with over 250,000 vertices in under two minutes on a Sun Sparc-10 workstation. For minimum-cost max-flow, the higher performance code available is CS, capable of solving instances of over 30,000 vertices in a few minutes on Sun Sparc-2 workstations. ● Andrew Goldberg's home page Problem Links ● Network Flow (10) ● Matching (9) ● Shortest Path (9) About the Book Send us Mail Go to Main Page This page last modified on Apr 23, 1997. file:///E|/WEBSITE/IMPLEMEN/GOLDBERG/IMPLEMEN.HTM [19/1/2003 1:36:37]

LEDA - A Library of Efficient Data Types and Algorithms LEDA - A Library of Efficient Data Types and Algorithms LEDA ("Library of Efficient Data types and Algorithms") has been developing since 1988 under the efforts of a group at the Max Planck Institut in Saarbrucken Germany (including Kurt Melhorn, Stefan Naher, Stefan Schirra, Christian Uhrig, and Christoph Burnikel). The success of LEDA has been a direct result of a continuous resource investment on the part of its algorithmically sophisticated development team. Implemented in C++ using templates, LEDA may be compiled on a wide range of systems (older compilers may not support templates, but most new C++ compilers provide facilities to implement this feature). The standard distribution contains source code, installation information, and a complete user's manual. Please note that LEDA is not in the public domain , but may be used freely for research and teaching. Commercial licenses are availabe through the LEDA home page. LEDA comprises an extensive collection of data structures and types. Libraries of algorithms using these data types are provided, with examples illustrating the ease with which algorithmic tasks may be accomplished given the LEDA data types. ● Download LEDA Files (German site) ● Download LEDA files (local site) ● Go to LEDA Home Page Problem Links ● Dictionaries (10) ● Graph Data Structures (10) ● Priority Queues (9) ● Connected Components (8) ● Robust Geometric Primitives (8) ● Intersection Detection (7) ● Maintaining Line Arrangements (7) ● Matching (7) ● Planarity Detection and Embedding (7) ● Point Location (7) ● Range Search (7) file:///E|/WEBSITE/IMPLEMEN/LEDA/IMPLEMEN.HTM (1 of 2) [19/1/2003 1:36:38]
