Examples with NodesShift org.vcell.util.graphlayout.NodesShift used on opensource projects

Example 1 with NodesShift

use of org.vcell.util.graphlayout.NodesShift in project vcell by virtualcell.

the class ShootAndCutMinimizer method minimize.

public void minimize(EnergySum energySum) {
    ContainedGraph graph = energySum.getGraph();
    for (Node node : graph.getNodes()) {
        double shiftX = ContainedGraphUtil.getRandomShiftX(node, random);
        double shiftY = ContainedGraphUtil.getRandomShiftY(node, random);
        while (Math.abs(shiftX) + Math.abs(shiftY) > 0.3) {
            NodesShift nodesShift = new NodesShift.SingleNode(graph, node, shiftX, shiftY);
            if (energySum.getDifference(nodesShift) < 0) {
                nodesShift.apply();
                break;
            }
            shiftX = (1 - cut) * shiftX;
            shiftY = (1 - cut) * shiftY;
        }
    }
