addDim

public abstract void addDim(String name, List<org.chocosolver.solver.variables.IntVar> l, int[] s, org.chocosolver.solver.variables.IntVar[] b)

Add a new dimension.

Parameters:

name - the dimension label

l - the capacity of each node. The variables *must be* ordered according to DefaultReconfigurationProblem.getNode(org.btrplace.model.Node).

s - The VM consumption

b - the placement variable for each VM. Same order than for s
