Query: Tuning Actions and Observables in Lattice QCD   We propose a strategy for conducting lattice QCD simulations at fixed volume
but variable quark mass so as to investigate the physical effects of dynamical
fermions. We present details of techniques which enable this to be carried out
effectively, namely the tuning in bare parameter space and efficient stochastic
estimation of the fermion determinant. Preliminary results and tests of the
method are presented. We discuss further possible applications of these
techniques.
