Example 6 with ScaleOperator

use of dr.inference.operators.ScaleOperator in project beast-mcmc by beast-dev.

the class NarrowExchangeTest method getOperatorSchedule.

public OperatorSchedule getOperatorSchedule(TreeModel treeModel) {
    Parameter rootParameter = treeModel.createNodeHeightsParameter(true, false, false);
    Parameter internalHeights = treeModel.createNodeHeightsParameter(false, true, false);
    ExchangeOperator operator = new ExchangeOperator(ExchangeOperator.NARROW, treeModel, 1.0);
    ScaleOperator scaleOperator = new ScaleOperator(rootParameter, 0.75, CoercionMode.COERCION_ON, 1.0);
    UniformOperator uniformOperator = new UniformOperator(internalHeights, 1.0);
    OperatorSchedule schedule = new SimpleOperatorSchedule();
    schedule.addOperator(operator);
    schedule.addOperator(scaleOperator);
    schedule.addOperator(uniformOperator);
    return schedule;
