Categorizing Work

The problems were categorized in 1998 and 1999 by a group of mathematics graduate instructors experienced at teaching in Treisman-style workshops (affiliations from 1999 are listed):

The classification effort was led by James Epperson and Eric Hsu, and was financially supported by Uri Treisman and the Dana Center.

The classification work was based on and inspired by work of James Epperson, Dara Sandow and Dick Stanley.
