Theoretical work has been compared to the scaffolding surrounding an edifice during construction. Without it, construction could not even begin. CSL has had a long history in building theoretical frameworks in many areas, including computational theory.
CSL did seminal work in computational geometry, most notably with the 3-D convex-hull algorithm and planar point location. This research applied to many areas, including the interaction between robots and the world.
In the 70s, CSL was one of the main centers for the emerging field of computational geometry. Franco Preparata's book, Computational Geometry, became the standard reference in the field.
CSL invented cube-connected cycles, an architecture for massively parallel processing (MPP). MPP computer systems boost processing speeds dramatically and avoid some of the bottlenecks in handling information.
