A new fish collection

Postby pjb » Sun Mar 22, 2020 6:37 am

When studying the Ultimate Fish Guide (http://forum.enjoysudoku.com/the-ultimate-fish-guide-t4993.html, UFG) thread, I was frustrated by the endless exemplars which lacked actual working examples. I was trying to create routines for standard fish, but lacked examples to test my code. Where there were actual examples, many times these had simpler fish that rendered redundant the more exotic fish. For this reason, I have confined my examples, which I present here, to fish that survive simpler fish. I define the examples following the base\cover terminology used at the start of the UFG.

In every case, the starting point is the grid arrived at after removing basics (naked and hidden singles, box/line interactions, locked and hidden sets). To produce the findings below, I used the following order of testing for fish. Within the categories, the order follows the listing below (ie each one has to survive the ones above). Using a different order would likely yield different results. In my solver, one needs to repearedly hit the "All" button to see these results described below. This only includes "standard fish", not "obi-fish" at this time.

Order of execution

finned and sashimi x-wings.

Franken Swordfish

Note that many examples have a franken or a mutant, depending on which you check for firstly. I have elected to detect franken fish first,
which makes finding mutants somewhat more difficult.
