SPOTLIGHT can make a sample of molecules even when no receptor is provided. To train our RL algorithm for generating molecules with desired properties, the molecules are first made in the vacuum, with the only energy terms coming from the self-energy. Since there is no Metropolis Monte-Carlo rejection (because there is no protein-ligand interaction energy), every completed molecule is accepted. A generation like this allows us to study the algorithm's properties without having protein scaffolds that could interfere with the generation by providing biases for some molecules to be more viable.
