Fig. 9: Sampling intensity maps of the Hf–Ta–C system in chemical composition space.
From: COPEX: co-evolutionary crystal structure prediction algorithm for complex systems

Data are generated from a COPEX and b USPEX. The map is colored according to the sampling intensity, divided into 23 × 20 bins, and the color bar refers to the number of sampled structures in each bin. The stable ternary compounds are marked by black circles.
