If it took you a year to grasp why the method works, and still don't get it, I suggest maybe spending your time on more productive things. If it's still unclear after all the diagrams, pictures, and the dozens of academic papers, not sure what more you'd expect (except some magic software that finds solution of 135 in less than 20 seconds maybe).
