through the population. Applications The diverse set of applications modeled with Pythagoras attest to its versatility and utility. Pythagoras has been used to study improvements to squad echelon night vision equipment in a peacekeeping scenario. It has been used to study tactics, techniques and procedures in response to a weapon of mass destruction attack on a military installation. Students at the Naval Academy have used it to study historical battles as diverse as The Battle of Ia Drang (one of the first US Army battles in Viet Nam), The Battle of Midway, and Chancellorsville. It was used to study tactics for using air-delivered ordnance to clear shallow water obstacles and mines. It is currently being used to support two different studies (one by Northrop Grumman and the other by students at the Naval Postgraduate School) of population dynamics in areas of the world where an insurgency is possible and the Marines are sent in to provide disaster relief after an earthquake. Requirements Pythagoras runs on a PC or any other platform that supports Java 1.5 and JAXB 2.0. It is particularly suitable for data farming — executing large numbers of repetitions of parametric runs to identify areas of unexpected behaviors and nonlinear results in a coevolving landscape. History Its heritage traces back to Project Albert, an international project dedicated to research in the human aspects of warfare, such as intangibles, co-evolving goals and non-linear relationships. Pythagoras originally began as a method by which the existing US Marine Corps-provided Archimedes model could be enhanced, modified, or controlled to enable it to run large problem sets on multiple platforms and be analyzed via data farming techniques on the Gilgamesh platform located at the Maui High Performance Computing Center (MHPCC).
