Getting started using Python virtual environment

1. Install python3-venv

sudo apt install python3-venv

2. Create virtual environment

python3 -m venv venv

3. Activate virtual environment

source venv/bin/activate

4. Install dependencies to your local virtual environment

pip install -r requirementx.txt

5. Now you're ready to start coding!

Running the application

Run with the default parameters:

python3 main.py

Show the help message:

python3 main.py --help

You can specify parameters using the following arguments:

python3 main.py --lattice_dimension 10 --entry_bound 73 --bkz_version 1 --svp_solver 1 --block_size 5 --precision default --repetitions 5

Running the test suite

You can run the existing tests with the following command

make test

OR manually using

pytest
