"The problem tackled by the Puget Sound teams asked them to design a mathematical model that would aid police investigators in tracking down serial criminals. The team had to create at least two schemes that would each generate a geographical profile of past crime scenes. After devising a technique to combine the two profiles and factoring in the times of the previous crimes, they had to predictor at least provide some guidanceas to the likely location of the next incident. The team had to tell investigators just how reliable their method was and provide any appropriate warnings about using the prediction in light of the uncertainties."
