All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<IKSolver.SearchStrategy>

Enclosing class:

IKSolver

public static enum IKSolver.SearchStrategy
extends java.lang.Enum<IKSolver.SearchStrategy>

Describes the search strategy used to help ensure convergence of the constrained non-linear least squares problem.

Enum Constant Summary

Enum Constants

Enum Constant and Description
BACKTRACK If a Newton step does not decrease the least-squares energy sufficiently, use an approximate line search to backtrack.
LEVENBERG_MARQUARDT Change step direction and size using Levenberg Marquardt stabilization.
NONE No strategy - simply do a (constrained) Newton solve to try and bring the gradient to zero at each step.

Method Summary

Modifier and Type	Method and Description
static IKSolver.SearchStrategy	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static IKSolver.SearchStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

NONE

public static final IKSolver.SearchStrategy NONE

No strategy - simply do a (constrained) Newton solve to try and bring the gradient to zero at each step.

BACKTRACK

public static final IKSolver.SearchStrategy BACKTRACK

If a Newton step does not decrease the least-squares energy sufficiently, use an approximate line search to backtrack.

LEVENBERG_MARQUARDT

public static final IKSolver.SearchStrategy LEVENBERG_MARQUARDT

Change step direction and size using Levenberg Marquardt stabilization.

Method Detail

values

public static IKSolver.SearchStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IKSolver.SearchStrategy c : IKSolver.SearchStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IKSolver.SearchStrategy valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
