## computeWeightedNodeOrderConstraintsScore

### Usage

computeWeightedNodeOrderConstraintsScore(TimeTree tree, RlRelativeNodeAgeWeightedConstraints constraints, RealPos beta)

### Arguments

 tree : TimeTree (pass by const reference) The tree which is used to compute the MRCA. constraints : RlRelativeNodeAgeWeightedConstraints (pass by value) The constraints on relative node ages that are needed to compute the score of the tree. beta : RealPos (pass by value) The beta weight for the constraints.
