Abstract

I survey recent work on symmetric computation. A number of strands of work, from logic, circuit complexity, combinatorial optimization and other areas have converged on similar notions of symmetry in computation. This write-up of an invited talk gives a whirlwind tour through the results and pointers to the relevant literature.
