First, clone the repository and install the dependencies:
git clone https://github.com/LCEOPT.git <LCEOPT_DIRECTORY>
cd <LCEOPT_DIRECTORY> && ./install_dependencies.sh
where <LCEOPT_DIRECTORY> is a directory of your choice.
Once completed, build LCEOPT via
mkdir -p build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=<INSTALL_DIRECTORY> ..
make -j <NUMBER_OF_BUILD_JOBS> && make install
where <INSTALL_DIRECTORY> is a directory of your choice.
After successfully building and installing LCEOPT, open a terminal and run
source <INSTALL_DIRECTORY>/share/oppt/setup.sh
This must be executed in each new terminal. Alternatively, add this line to your ~/.bashrc file. In the same terminal, run
<LCEOPT_DIRECTORY>/bin/lceopt --cfg <LCEOPT_DIRECTORY>/ProblemEnvironments/<PROBLEM>/cfg/<PROBLEM_CONFIG_FILE>.cfg
For instance, to run the ContTag problem, run
<LCEOPT_DIRECTORY>/bin/lceopt --cfg <LCEOPT_DIRECTORY>/ProblemEnvironments/ContTag/cfg/ContTag.cfg
Our implementation of LCEOPT uses the following third-party libraries:
