An article last Friday, “MIT’s Endowment Over the Past Ten Years” contained several errors. MIT’s endowment payout is expected to drop in fiscal year 2011 (July 1, 2010 through June 30, 2011), not the current fiscal year (FY2010). The payout dropped twice in the 2000s — from FY2003 to FY2004 and from FY2004 to FY2005 — not once, making the projected drop in FY2011 the third in history, not the second. MIT now plans to reduce its budget by $118–$128 million over two years instead of $150 million over three years as originally planned (not a revised $150 million over two years).

An article Tuesday about the new edition of Introduction to Algorithms by Thomas H. Cormen PhD ’93, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein PhD ’92 incorrectly claimed that Cormen implemented every algorithm in the new book. Cormen implemented every algorithm in Parts I-VI and every new algorithm in the third edition.

Cormen is chair of the Department of Computer Science at Dartmouth College, not “Darthmouth.” “Darthmouth is what James Earl Jones’s voice comes out of,” Cormen said.
