- 1 Building a generative model with a dynamic graph is hard to achieve on a periodic structure compared to organic molecules.
- 2 We conducted experiments on the Materials project dataset to evaluate the performance of our tool.
- 3 Graph generation is performed by exploring the direct repetition of a cell, starting by evaluating the adjacent cell and extending the search area until we find all the edges.
- 4 It can also be used to produce hydrocarbons from CO2 to help reduce the carbon footprint of human activities.
Introduction
High-throughput screening based on machine learning models is largely employed to obtain materials with desired properties in the fundamental challenge of new materials discovery in material sciences. Crystalline material generation has recently received considerable attention.
We are interested in generating new crystal materials for developing new solar panels with a band gap enabling hydrolyse.
This helps to solve problems related to clean energy production and storage, which is one of the major challenges facing our society.
Organic molecules are composed of wide carbon chains with a limited variety of atoms, while crystal materials are three-dimensional periodic structures composed of a wide variety of chemical bonds and atoms.
Methodology
Our graph generation method is built upon two main parts: a searching algorithm and an ordered stack. We compare the generation time of one batch with various KNN settings and batch sizes to check the time complexity of our method.

It can also be used to produce hydrocarbons from CO2 to help reduce the carbon footprint of human activities. The periodic structure of crystals makes graph processing difficult when training a generative model, particularly in a massively parallel environment, unlike the straightforward generation of graph-based representations of organic molecules.

is an infinite set of triplet that represents all possible materials with n atoms.
The projections may not be injective.
Crystallographic Graph Generation
This section defines crystalline structures as clouds of atoms with periodic repetition patterns. It explains the complexity of representing these structures graphically due to their three-dimensional nature and local environments.
Crystallographic Graph
The section describes the definition of a graph associated with crystal materials as an oriented graph, detailing the representation of edges and nodes. It references previous works and formal definitions related to crystalline structures.
Generation Process
The generation process adapts to the periodic nature of crystals by exploring cell repetitions in a torus space. It outlines the searching algorithm and ordered stack used to efficiently generate graphs while managing RAM usage.
