Specified by:

inject in interface Injectable

Overrides:

inject in class AbstractCumulatives

Parameters:

ps - the scheduler parameters

rp - the problem

Returns:

true if the injection succeeded, false if the problem is sure to not have a solution

Throws:

SchedulerException - if an error occurred while injecting.

addDim

public void addDim(List<org.chocosolver.solver.variables.IntVar> c, int[] cUse, org.chocosolver.solver.variables.IntVar[] dUse)

Add a dimension.

Specified by:

addDim in interface Cumulatives

Parameters:

c - the resource capacity of each of the nodes

cUse - the resource usage of each of the cSlices

dUse - the resource usage of each of the dSlices

beforeSolve

public boolean beforeSolve(ReconfigurationProblem rp)

Build the constraint.

Specified by:

beforeSolve in interface ChocoView

Parameters:

rp - the problem we solve

Returns:

the resulting constraint
