The Indexing Waltz

Waltz of the chromosomes

cientists have discovered a new function for amyloid precursor protein (APP), a protein linked to Alzheimer’s disease. The finding may reveal how APP gets mixed up with the enzymes that make it go bad. APP has an evil reputation. The and secretases transform it into amyloidpeptide, a component of the plaques that riddle the brain in Alzheimer’s disease. Previous work by Larry Goldstein (Univesi...

Remembering Dave Waltz (1943-2012)

David L Waltz, in Memoriam

tion after completing his dissertation in 1972 at the Massachusetts Institute of Technology Artificial Intelligence Laboratory (MIT AI Lab). That dissertation created the field of constraint propagation by showing that constraints and a rich but simple descriptive system were sufficient to recover threedimensional information from a two-dimensional projection. Besides an education, Dave picked ...

Waltz Filtering in Java with JSolver

This paper uses the Waltz Filtering Algorithm and the Line-Labelling Problem to illustrate how AI algorithms can easily be implemented using Java and JSolver2 – a constraint-programming class library. The Waltz Filtering Algorithm popularised the technique of constraint propagation – the cornerstone for algorithms to solve constraint-satisfaction problems (CSP). It was initially developed as a ...
