\chapter{Version History}
|
|
\section*{1.2.0}
|
|
\subsection{New Features}
|
|
\begin{itemize}
|
|
\item \texttt{CXSparse} support.
|
|
\item Block oriented fill reducing orderings. This
|
|
reduces the factorization time for sparse
|
|
\texttt{CHOLMOD} significantly.
|
|
\item New Trust region loop with support for multiple
|
|
trust region step strategies. Currently only Levenberg-Marquardt is supported, but this refactoring opens the door for Dog-leg, Stiehaug and others.
|
|
\item \texttt{Cmake} file restructuring. Builds in \texttt{Release} mode by default, and now has platform specific tuning flags.
|
|
\item Re-organized documentation. No new content, but better organization.
|
|
\end{itemize}
|
|
|
|
\subsection{Bug Fixes}
|
|
\begin{itemize}
|
|
\item Fixed integer overflow bug in \texttt{block\_random\_access\_sparse\_matrix.cc}.
|
|
\item Renamed some macros to prevent name conflicts.
|
|
\item Fixed incorrent input to \texttt{StateUpdatingCallback}.
|
|
\item Fixes to AutoDiff tests.
|
|
\item Various internal cleanups.
|
|
\end{itemize}
|
|
|
|
\section*{1.1.1}
|
|
\subsection{Bug Fixes}
|
|
\begin{itemize}
|
|
\item Fix a bug in the handling of constant blocks. Thanks to Louis Simard for reporting this.
|
|
\item Add an optional lower bound to the Levenberg-Marquardt regularizer to prevent oscillating between well and ill posed linear problems.
|
|
\item Some internal refactoring and test fixes.
|
|
\end{itemize}
|
|
\section{1.1.0}
|
|
\subsection{New Features}
|
|
\begin{itemize}
|
|
\item New iterative linear solver for general sparse problems - \texttt{CGNR} and a block Jacobi preconditioner for it.
|
|
\item Changed the semantics of how \texttt{SuiteSparse} dependencies are checked and used. Now \texttt{SuiteSparse} is built by default, only if all of its dependencies are present.
|
|
\item Automatic differentiation now supports dynamic number of residuals.
|
|
\item Support for writing the linear least squares problems to disk in text format so that they can loaded into \texttt{MATLAB}.
|
|
\item Linear solver results are now checked for nan and infinities.
|
|
\item Added \texttt{.gitignore} file.
|
|
\item A better more robust build system.
|
|
\end{itemize}
|
|
|
|
\subsection{Bug Fixes}
|
|
\begin{itemize}
|
|
\item Fixed a strict weak ordering bug in the schur ordering.
|
|
\item Grammar and typos in the documents and code comments.
|
|
\item Fixed tests which depended on exact equality between floating point values.
|
|
\end{itemize}
