Materials prediction and discovery accelerated with bio-inspired algorithms

Evolutionary search, particle swarm optimization, and other recently introduced structure prediction methods have shown great promise for accelerating materials discovery. Yet, the number of confirmed predictions remains relatively low, especially in the field of superconductivity. We have employed a combination of high-throughput screening, targeted evolutionary search [1], and rational design to systematically examine over 12,000 metal-boron compounds [2]. This largest ab initio scan of the complex materials class has uncovered dozens of new exotic materials, some of which have already been synthesized in joint experiments [3-5]. In particular, the proposed and confirmed FeB4 compound with a previously unknown crystal structure appears to be the first superconductor developed fully in silico [5-7]. I will overview the prediction strategies and describe our on-going work using an emerging neural network methodology to accelerate materials development.
