  We use Langevin dynamics simulations to study dense two-dimensional systems
of particles where all binary interactions are different (AID) in the sense
that each interaction parameter is characterized by a randomly chosen number.
We compare two systems that differ by the probability distributions from which
the interaction parameters are drawn: uniform (U) and exponential (E). Both
systems undergo neighborhood identity ordering (NIO) and form metastable
clusters in the fluid phase near the liquid-solid transition but the effects
are much stronger in E than in U systems. Possible implications of our results
for the control of the structure of multicomponent alloys are discussed.
