Before revision:  In this work, a new de novo molecular design framework is proposed based on a sequential graph generator . Compared with previous graph generative models, the proposed method is much more tuned for molecule generation and have been scaled up to cover significantly larger molecules in the ChEMBL database.
After revision:  In this work, a new de novo molecular design framework is proposed based on a type sequential graph generators that do not use atom level recurrent units . Compared with previous graph generative models, the proposed method is much more tuned for molecule generation and have been scaled up to cover significantly larger molecules in the ChEMBL database.
