 Author: pharosian  [ Sat Dec 07, 2013 5:35 am ] Post subject: Re: Use of the "clear all non-bolded" I solve the puzzles almost exclusively on the computer. As I go along, I mark the cells that are "given" in bold. By "given," I mean not only the single cells, but also the ones that have only one possibility based on their relationship to single cells, or cells that have to be 0 because of the intersection of a vertical and horizontal cage that are 0x or 0:.From there, I move on to filling in the rest---but sometimes I reach a point where I realize my logic failed at some point and I have to start over. But rather than go all the way back to no cells filled in, I use the clear all non-bolded cells so at least I don't have to repeat the process of filling in the "givens."I'm pretty good about saving at points where I'm (fairly) confident of all my entries to that point, and in a case like that, I just refresh the page and it brings me back to a state that includes some cells that are filled in as definite but not bolded as well as pencil marks... but sometimes I either forget to save or there is simply too much wrong and I need a more drastic option.If I never made a mistake, I would never need the clear all or clear all non-bold... but unfortunately every once in a while I make a bad assumption or a bad calculation or I fail to notice a typo, and that poisons everything that follows, so having a way to preserve at least the bolded cells is a benefit.

But I also use it in different circumstances: sometimes when I think I am dealing with a very difficult or "curious" puzzle, once the "easier" numbers are bolded, I advance to the solution leaving the rest unbolded, at some point I save the diagram so, after sending the solution, later during the day or the following days, if I have time , I can recall the diagram, and start again from the bolded cells just to enjoy it or to study its properties.
