BatchLeastSquaresOD.SolutionDampingOption Property

DescriptionThe options for damping the convergence of the solution.
The LevenburgMarquardt damping method uses the SolutionDampingFactorDecrease, and SolutionDampingFactorIncrease properties to scale the SolutionDampingFactor based on the SolutionDampingRho and SolutionDampingRhoTolerance properties in order to improve the convergence of the Batch Least Squares solution. Rho is a quality factor to quantify the quality of the state update compared to the prestate update. A larger Rho corresponds to a higher quality state update. If Rho is large compared to RhoTolerance, the Factor will be scaled down by a factor of FactorDecrease. If Rho is less than the RhoTolerance, the Factor will be scaled up by a factor of FactorIncrease.
The Quadratic damping method is the more robust, but slower method of the two. It uses the SolutionDampingFactor and SolutionDampingAlpha properties based on the SolutionDampingRho and SolutionDampingRhoTolerance properties in order to improve the convergence of the Batch Least Squares solution. Similar to the LevenburgMarquardt method, the Quadratic damping method uses Rho depending on RhoTolerance to scale the Factor or not. However, the amount the Factor is scaled is determined by Alpha instead of the FactorDecrease and FactorIncrease properties. In the Quadratic damping method the Factor is only scaled if Rho is below RhoTolerance.
