Symmetry within and between solutions
Symmetry can be used to help solve many problems. For instance, Einstein's famous 1905 paper ("On the Electrodynamics of Moving Bodies") uses symmetry to help derive...

On Quadratic Threshold CSPs
A predicate P : {−1, 1}k → {0, 1} can be associated with a constraint satisfaction problem Max CSP(P). P is called “approximation resistant” if Max CSP(P) cannot be approxi...

Faster symmetry discovery using sparsity of symmetries
Many computational tools have recently begun to benefit from the use of the symmetry inherent in the tasks they solve, and use general-purpose graph symmetry tools to uncover this...

Massively multi-topology sizing of analog integrated circuits
This paper demonstrates a system that performs multiobjective sizing across 100,000 analog circuit topologies simultaneously, with SPICE accuracy. It builds on a previous system, ...
