Adults' Perceived Prevalence of Enteric Fever Predicts Laboratory-validated Incidence of Typhoid Fever in Children (2008)

Chen, Xinguang, Stanton, Bonita, Pach, Al, Nyamete, Andrew, Ochiai, R. Leon, Kaljee, Linda, ...

This study was undertaken to develop a model to predict the incidence of typhoid in children based on adults' perception of prevalence of enteric fever in the wider community. Typhoid cases among...

Constraint Programming Lessons Learned from (2001)

Adam Beacham, Xinguang Chen, Jonathan Sillito, Peter Van Beek

Constraint programming is a methodology for solving di- cult combinatorial problems. In the methodology, one makes three design decisions: the constraint model, the search algorithm for solving the...
