Equivalence classes of clone circuits for physical-design benchmarking
To provide a better understanding of physical design algorithms and the underlying circuit architecture they are targeting, we need to exercise the algorithms and architectures wi...

Alpha-shapes and flow shapes are homotopy equivalent
In this paper we establish a topological similarity between two apparently different shape constructors from a set of points. Shape constructors are geometric structures that tran...
