Example 1 with IntValueSelector

use of org.chocosolver.solver.search.strategy.selectors.values.IntValueSelector in project scheduler by btrplace.

the class CMinMigrations method placeVMs.

/*
     * Try to place the VMs associated on the actions in a random node while trying first to stay on the current node
     */
private void placeVMs(Parameters ps, List<AbstractStrategy<?>> strategies, List<VMTransition> actions, OnStableNodeFirst schedHeuristic, Map<IntVar, VM> map) {
    IntValueSelector rnd = new WorstFit(map, rp, new BiggestDimension());
    if (!useResources) {
        rnd = new RandomVMPlacement(rp, map, true, ps.getRandomSeed());
    }
    IntVar[] hosts = dSlices(actions).map(Slice::getHoster).filter(v -> !v.isInstantiated()).toArray(IntVar[]::new);
    if (hosts.length > 0) {
        strategies.add(new IntStrategy(hosts, new HostingVariableSelector(rp.getModel(), schedHeuristic), rnd));
