We point out that large-N_c QCD in the 't Hooft limit is equivalent to SO(2*N_c)
Yang-Mills with fundamental fermions. In the latter, notorious "sign problem" is absent even with finite baryon chemical potential, and hence the Monte-Carlo study is tractable. We also show the same idea can be applied in related models -- chiral random matrix theory (RMT) and holographic models. We explain nice old results like the exactness of the phase quenching in RMT in a certain parameter region is naturally understood and is generalized from the point of view of the equivalence.
