This is the repository of the Dynamic Hashed Blocks (DHB) format.

For a detailed discussion of DHB and a comparison with other graph data structures please read the paper A Fast Data Structure for Dynamic Graphs Based on Hash-Indexed Adjacency Blocks (2022) available on the Dagstuhl Research Online Publication Server (DROPS).

Build the library using CMake (e.g., with the generator Ninja).

mkdir build
cd build
cmake -GNinja -DCMAKE_BUILD_TYPE=Release ..
ninja

You must clone this repository recursively in order to obtain catch2 which is necessary for our test environment using:

git clone --recursive https://github.com/hu-macsy/dhb.git

If you forgot to clone recursive, simply update with initialisation:

git submodule update --init --recursive

You can then build the tests by setting the CMake option DHB_TEST to On.

cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DDHB_TEST=On ..
ninja
