A direct-sampling path planner with a 'bad phase purge' transformation finds CALPHAD-valid composition gradients in 5 to 9 element systems using orders of magnitude fewer thermodynamic calculations than surrogate modeling.
The algorithmic foundations of these hybrid methods for collision checking have already been developed in the path planning community [23]

On-the-Fly Path Planning for the Design of Compositional Gradients in High Dimensions
A direct-sampling path planner with a 'bad phase purge' transformation finds CALPHAD-valid composition gradients in 5 to 9 element systems using orders of magnitude fewer thermodynamic calculations than surrogate modeling.
