A header-only C++ library for L-BFGS and L-BFGS-B algorithms
Trying to test LBFGS++ on Linux/ppc64le leads to the example programs in this repository hanging. Test log ``` + set -ex + for i in 'examples/*.cpp' + /home/conda/feedstock_root/build_artifacts/lbfgspp_1656534905612/_test_env_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehol/bin/powerpc64le-conda-linux-gnu-c++ -fvisibility-inlines-hidden -std=c++17...
My problem is with optimizing the log marginal likelihood of a Gaussian Process. I was wondering if there was any comparison done between LBFGSpp and scipys lbfgsb. Or perhaps, how...
Hi, first off, I want to say that this is just a great library and a joy to use. Clean header-only modern C++ with Eigen, what's not to like? :)...
I was wondering whether you would be interested in a patch that removed runtime exceptions, opting instead for returning either a boolean, enumeration or some sort of `std::optional` value to...
Hi, thanks for writing this library! While using it, I encountered the following runtime error, `terminate called after throwing an instance of 'std::runtime_error' what(): the line search routine reached the...
Hi Xuan, this is an amazing library; it is especially helpful how you set it up as most objective functions do have so many other parameters that are not the...
Hi Prof. Yi Xuan, Thank you for sharing this library. I don't know much about optimization and C++ functors. I am trying to convert an optimization problem from Python SciPy...
In LineSearchNocedalWright.h (line 145, 146): step = (fx_hi - fx_lo) * step_lo - (step_hi * step_hi - step_lo * step_lo) * dg_lo / 2; step /= (fx_hi - fx_lo) -...
I am questioning if there is an issue with Step 3 of finding the Cauchy Point. You are updating the vector 'p' during the loop, but according to the paper,...
Hey, I am using this nice header-only LBFGS implementation to provide a geometry optimisation method in my molecular modelling program (https://github.com/conradhuebler/curcuma). In order to have more control over the optimisation...
