It's actually a register allocation problem.


I'm looking for an algorithm to color a graph with exact N colors,
usually N is larger than the chromatic number of the graph. However,
the number of occurrences of each color is expected to be the same, in
probability. That is, each color is used as roughly many times to
color the graph.


In the other words, the vertices are partitioned into N independent
sets, and the number of vertices in each indepedent set shoudl be
roughly the same.
