Integer Programming Down Under: Theory, Algorithms and Applications

July 6—8, 2011

Newcastle NSW Australia

Sponsored by CARMA , AMSI, AustMS, and CMIS

The IPDU (Integer Programming Down Under) workshop is designed to bring together researchers with an interest in the theory, algorithms and applications of integer programming so as to facilitate an exchange on the latest ideas and developments in the area, and to provide a venue and environment for informal interaction and collaborative engagements.

The workshop will be held in Newcastle in the week immediately preceding IFORS 2011, which will occur in Melbourne on July 10—15, 2011.

Newcastle is only a two-hour drive north of Sydney and a short flight from Melbourne (with Jetstar or Virgin Blue), with direct fights also available from Brisbane. Newcastle is located adjacent to the Hunter Valley, a world-famous wine-producing region, and boasts beautiful beaches and bushland. It features in Lonely Planet's Top 10 Cities for 2011 list. It is also home to the world's largest coal export operation.
