Wave Function Collapse Sudoku Solution

Simple implementation of Wave Function Collapse algorithm for solving sudoku puzzle. Can be used via CLI with:

adventure wfc-sudoku

Can output individual steps of solution.

Sometimes fails due to random choices that lead to cases with impossible solutions

Example:

Voronoi

Very simple and not optimal in terms of complexity ($O$-notation) implementation of algorithm for generating Voronoi Diagrams.

Provides 3 distance functions:

Euler

Default distance function, widely known by everyone.

$$ \sqrt{(x_1 - x_2) ^ 2 + (y_1 - y_2) ^ 2} $$

Manhattan

Also known as "taxicab" distance, calculated as length of vertical and horizontal moves from one position to another.

$$ |x_1 - x_2| + |y_1 - y_2| $$

Chebyshev

Distance function calculated as max difference between $x$ and $y$ of positions.

$$ \max (|x_1 - x_2|, |y_1 - y_2|) $$

For generating random centers of groups I also provide 3 different approaches:

Approach	Description
Random	Generates random $x$ & $y$ for each group center; Guarantees generation of exact number of groups
Min Distance Random	Generates random $x$ & $y$ for each group center; Guarantees generation of exact number of groups and minimal distance between group center
Fuzzy Grid	Builds a grid of evenly distributed center and than based on fuzz radius randomly moves them around initial position
