This isn't an exact answer as for how to construct NCSort. However, it is the core of my approach for generating Wick contractions. I ripped out all the bells and whistles. It helps to have some background: I do lattice QCD, and so I mostly think about quark contractions. So, if you see "quark" you can parse that as "fermion". My code is designed to ...

As noted in the question, the first code segment does run to completion. However, NDSolve also issues two warning messages. NDSolve::ibcinc: Warning: boundary and initial conditions are inconsistent. >> NDSolve::eerr: Warning: scaled local spatial error estimate of 37.88105237757757at t = 100. in the direction of independent variable x is much ...
