I find that **pymatgen.analysis.phase_diagram** can construct a convex hull of a system. But,I failed to catch on the Mathematical principle of the method by reading source program. So, do you have any literatures about how to construct a convex hull and how to define energy above hull (Especially in high dimension)? I have read the literatures that you given in the source program, but they only show the results without methods.

Sorry for bother you again!

hope for your reply!
