We study the effects of Wilson fermions in Su(3) lattice gauge theory by an algorithm considering the fermion determinant exactly. We use lattices of size 4/sup 3/ x 2 and 4/sup 4/. A comparison is made with the outcomes of fast approximate algorithms of the bush-factorized type. Our results point to the occurrence of a phase transition near ..beta.. = 5.3 and kappa = 0.14. We discuss the relation of this phase transition to that observed recently with Kogut-Susskind--type fermionic action.
