Please comment the code!

[10maurycy10]

Comments make reading and debugging the code much easier.

They are especially necessary if the code has one letter variable names!

I agree. Will add a few comments when I have time. Right now I can say that in SimpleTiledModel.cs a is a 90 degrees rotation, and b is tile reflection.

hello，what's the meaning of symmetry?
cardinality ?
func a b ?

need some comments. thanks..
or is any place we can talk about wfc . maybe anybody need some help or communicate.

hello，what's the meaning of symmetry?

Google it.

cardinality ?

Google it.

Comments are not the place for defining basic mathematical terms.

[segrallx]

thank you , i still consued about the meaning of X ,F, L ,T
could you tell me what symmetry they are representing?

[mxgmn]

X, F, L, T are types of tile symmetries. X means a fully symmetric tile: you can rotate it 90, 180, 270 degrees or reflect it, and it would still look the same (like letter X). L can be reflected along the line y=x. F has no nontrivial symmetries.

[ldo]

Cardinality: how many orientations (excluding reflection) of a tile with this symmetry can be distinguished.

Func<int, int> a, b: I call a the rotate_func — the function that transforms the index of a tile orientation to the one for the next 90° rotation anticlockwise — and b the reflect_func — the function that transforms the index of a tile orientation to the one for the reflected version.

Also worth pointing out that all the quantum mumbo-jumbo is a complete red herring. If you want a physical analogy, use the term “phase change”.
