Topology optimization using polytopes [PDF]
Computer Methods in Applied Mechanics and Engineering, 2015 Meshing complex engineering domains is a challenging task. Arbitrary polyhedral meshes can provide the much needed flexibility in automated discretization of such domains. The geometric property of the polyhedral meshes such as the unstructured nature and the facial connectivity between elements makes them specially attractive for topology optimization

Neural networks for topology optimization [PDF]
Russian Journal of Numerical Analysis and Mathematical Modelling, 2019 Abstract In this research, we propose a deep learning based approach for speeding up the topology optimization methods. The problem we seek to solve is the layout problem. The main novelty of this work is to state the problem as an image segmentation task.

Optimal transportation, topology and uniqueness [PDF]
Bulletin of Mathematical Sciences, 2011 The Monge-Kantorovich transportation problem involves optimizing with respect to a given a cost function. Uniqueness is a fundamental open question about which little is known when the cost function is smooth and the landscapes containing the goods to be transported possess (non-trivial) topology.
