Package pal.tree

Class LogParameterizedTree

java.lang.Object
pal.tree.ParameterizedTree.ParameterizedTreeBase
pal.tree.LogParameterizedTree
All Implemented Interfaces:
Serializable, IdGroup, Parameterized, Units, UnitsProvider, ParameterizedTree, Tree
public class LogParameterizedTree extends ParameterizedTree.ParameterizedTreeBase implements ParameterizedTree
This class logarithmically transforms tree parameters. Hopefully this makes the function look more like a quadratic for the optimizer!
