Review of unquenched results

One of the major frontiers of lattice field theory is the inclusion of ligh t fermions in simulations, particularly in pursuit of accurate, first princ iples predictions from lattice QCD. With dedicated Teraflops-scale computer s currently simulating QCD, another step towards precision full QCD simulat ions is underway. In addition to ongoing staggered and Wilson fermion simul ations, first results from full QCD with domain wall fermions are available . After some discussion of work toward better algorithms, simulations compl eted to date will be discussed.
