I describe a new way of constructing a gauge action that eliminates scaling artifacts, by writing the continuum formalism in terms of "gauge links" (Schwinger line integrals) and using the optimal SLAC representation of the lattice derivative. Computational performance can be maintained by implementing the action as a "stochastic" operator, as has been recently implemented in the MILC code for the optimal D-slash operator and the antialiasing filter.
