In 2006, INFORMS Optimization Society started organizing biannual conferences. These conferences are centered around a theme and happen in the “off” years of the ICS (INFORMS Computing Society) conferences. The third OSC (Optimization Society Conference) will be held in Gainesville, Florida on February 26 – 28, 2010. The theme of this one is Energy, Sustainability and Climate Change.
