Here is a great article about why computerized routing programs frequently generate "optimal" results that folks don't understand, and thus "aren't good": http://www.optaplanner.org/blog/2013/08/06/FalseAssumptionsForVRP.html

2013 Most Motivated Student, future CPA

Using a scientifically sound approach, researchers at the McCombs School of Business divided incoming freshmen into three accounting classes: a control, one with occasional light beatings, and another with regular, intense sessions. Researchers were unable to make the study double-blind, as the sampling was obvious to any outside observer, as well as the participants.

After analyzing their results, and comparing individual performances to the wider average, a strong correlation was discovered. Workers, er -- Students in the third group demonstrated higher skills aptitude, and an increased motivation and ability to learn the material quickly. They also displayed higher group creative skills, and paradoxically, an statistically relevant increase in days absent.

Researchers plan to evaluate future scenarios, including applications in IT departments, variations for middle managers, as well as pilot programs at local elementary schools.
