Changelog for ceres-solver-debugsource-2.1.0-bp155.1.5.x86_64.rpm :

* Sat Feb 04 2023 Stefan Brüns - Update to version 2.1.0.
* New Features: + Support for CUDA based dense solvers - DENSE_QR, DENSE_NORMAL_CHOLESKY & DENSE_SCHUR (Joydeep Biswas, Sameer Agarwal) + Manifold is the new LocalParameterization. Version 2.1 is the transition release where users can use both LocalParameterization as well as Manifold objects as they transition from the former to the latter. LocalParameterization will be removed in version 2.2. There should be no numerical change to the results as a result of this change. (Sameer Agarwal, Johannes Beck, Sergiu Deitsch) + A number of changes to Jet s (Sergiu Deitsch): - Jet gained support for, copysign, fma (fused multiply-add), midpoint (C++20 and above), lerp (C++20 and above), 3-argument hypot (C++17 and above), log10, log1p, exp1m, norm (squared norm). - Quiet floating-point comparison: isless, isgreater, islessgreater, islessequal, isgreaterequal, isunordered, signbit, fdim - Categorization and comparison operations are applied exclusively and consistently to the scalar part of a Jet now: isnan, isinf, isnormal, isfinite, fpclassify (new), fmin, fmax - It is now possible to safely compare a Jet against a scalar (or literal) without constructing a Jet first (even if it’s nested) This enables interaction with various arithmetic functions that expect a scalar like instance, such as boost::math::pow<-N> for reciprocal computation. + Add NumericDiffFirstOrderFunction (Sameer Agarwal)
* Backward Incompatible API Changes: + LocalParameterization is deprecated. It will be removed in version 2.2. Use Manifold instead. + Classification functions like IsFinite are deprecated. Use the C++11 functions (isfinite, isnan etc) going forward. However to maintain consistent behaviour with comparison operators, these functions only inspect the scalar part of the Jet.
* Many Bug Fixes & Minor Changes, for details, see http://ceres-solver.org/version_history.html- Drop upstream fix-tbb-2021.1-detection.patch- Use memory-constrains to avoid occasional OOM build failures
* Mon Feb 21 2022 Stefan Brüns - Fix build with TBB >= 2021.1, add fix-tbb-2021.1-detection.patch- Correct License tags.- Cleanup spec file, remove obsolete CMake options.- Add _constraints to avoid occasional build failures.
* Sat Jan 16 2021 andy great - Update to version 2.0.0.
* C++ threading based multi-threading support.
* Problem::AddResidualBlock(), SizedFunction, AutoDiffCostFunction, NumericDiffCostFunction support an arbitrary number of parameter blocks using variadic templates
* Significantly faster AutoDiff
* Mixed precision solves when using SPARSE_NORMAL_CHOLESKY.
* LocalParameterization objects can have a zero sized tangent size, which effectively makes the parameter block constant. In particular, this allows for a SubsetParameterization that holds all the coordinates of a parameter block constant.
* Visibility based preconditioning now works with Eigen and CXSparse.
* Added Problem::EvaluateResidualBlock() and Problem::EvaluateResidualBlockAssumingParametersUnchanged().
* GradientChecker now uses RIDDERS method for more accurate numerical derivatives.
* Covariance computation uses a faster SVD algorithm
* A new local parameterization for lines
* A new (SUBSET) preconditioner for problems with general sparsity.
* Faster Schur elimination using faster custom BLAS routines for small matrices.
* Automatic differentiation for FirstOrderFunction in the form of AutoDiffFirstOrderFunction.
* TinySolverAutoDiffFunction now supports dynamic number of residuals just like AutoDiffCostFunction.
* Backward Incompatible API Changes
* EvaluationCallback has been moved from Solver::Options to Problem::Options for a more correct API.
* Removed Android.mk based build.
* Solver::Options::num_linear_solver_threads is no more.
* Several other moinor fixes and changes
* Thu Sep 17 2020 Dirk Stoecker - libceres-devel requires glog-devel- cleanup spec-file format
* Tue Jan 01 2019 Jan Engelhardt - Rename %soname to %sover to better reflect its use.- Trim filler wording from description.
* Fri Jun 29 2018 herbertAATTgraeber-clan.de- Use a _service file for download and compression- Update to version 1.14.0
* New EvaluationCallback API. (Keir Mierle)
* TBB based threading (Yury Prokazov & Mike Vitus)
* C++11 threads based threading (Mike Vitus)
* A ceres::Context object to cache and keep track of global state. (Mike Vitus)
* TinySolver - A small dense solver meant for solving small problems really fast. [EXPERIMENTAL] (Keir Mierle & Sameer Agarwal)
* Bazel Build. (Keir Mierle & Rodrigo Queiro)
* Several other moinor fixes and changes- Update to version 1.13.0
* LineSearchMinimizer and GradientProblemSolver are up to 2x faster due to fewer function evaluations. (Sameer Agarwal)
* SPARSE_NORMAL_CHOLESKY is significantly faster because Ceres now computes the normal equations exploiting the static block sparsity structure. (Cheng Wang & Sameer Agarwal)
* Add compound with scalar operators for Jets. (Alex Stewart)
* Enable support for AVX instructions for Jets. (Alex Stewart)
* Several other moinor fixes and changes
* Sat Mar 25 2017 herbertAATTgraeber-clan.de- Initial package (Eigen-only)
