after the fact

Some criteria can be achieved after-the fact. So far these after-the-fact modifications are compatible. But the speed of the calculation is also a potential concern.

Non self-depreciation(NSD)

If a trust metric has self depreciation, this can be removed simply by removing the outward edges of trust recipients. I.e. H(G,y)={e∈G : origin(e)≠y} and

  h_G(x,y) = f_H(G,y)(x,y)

Self-confidence(SC)

Similarly, self-confidence can be achieved by removing the edges towards self; H(G,x)={e∈G : origin(e)≠x} and

  h_G(x,y) = f_H(G,x)(x,y)
