Enemy AI that even pathfinds around each other (starcraft)

I understand how pathfinder works against solid objects. However, how do you create enemy AI that runs towards the player, but never overlaps other enemies, never does a jiggle dance, or bounce like a bullet when bumping up against each other? The desired effect would be similar to how Starcraft enemies chase after you.

in starcraft they enter into each other (sc1) - so you would have to make them without collision detecting between them with pathfinding. oh yeah, and not solids.

Oh woops sorry. SC2 - not 1. They don't overlap in 2.

then just add solid to your enemies and they will evade each other. of course you will have to update pathfinding obstacle map regularly because now even the moving ships are obstacles to each other. use on that family - regenerate obstacle map, on each 0.2 sec. (doing it on each tick would blow up performance needs)

This solid behavior makes the enemies move around erratically, They jiggle and bounce all crazy like.
