Have you looked at same charge repulsion ? Each point get a contribution
/ movement on the opposite direction from each other point, and the
strength is proportionally inverse to the square of the distance between
the points.

For N points, you need to evaluate (N)*(N-1)/2 pairs.

You can add complexity by using a different mass for each point, and
dividing the strength by the mass to compute the movement of each step.

Another extension would be "negative gravity", taking into account the
mass of the other point when computing the strength.

You can also explore the domain of replacing the inverse square of
distance by other formulae (constant, linear, cube, log or exp,
fractional power such as 1.6 or 2.4, ... )
