Overview

Zero Defect

• mondrian.jl: Backtracking with top-left-heuristic to check if a defect of 0 for a given n is possible. Single- and Multi-threaded functions are available.
• Old/mondrian-ideas.jl: Alternative approaches using Integer Programming and Knuth's Dancing Links algorithm which tend to be slower in practise.

Minimal Defect

• mondrian-defect.jl: Parallelized search for the minimal defect of a given n using Integer Programming and Backtracking
• Old/mondrian-defect/mondrian.jl: Alternative approaches which tend to be slower in practise.
