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.
Here, the number of collision checks was reduced by relaxing the constraints (i.e., allowable fraction of bad phases)
