I have thoroughly analyze the XY-Wing and XYZ-Wing Transport examplars and overhaul the routines in my RJSudoku.c and RJSukaku.c programs.

Wish to inform that, both the programs are now searched all single-links (strong and weak) Transport moves mentioned in Patterns.txt file:

1) XY-Wing Type 1 Transport (78 examplars)
2) XYZ-Transport (56 examplars)
3) XY-Wing Type 2 Transport (32 examplars)
4) XYZ-Wing Transport (34 exemplars)

Find below statistics of few small known puzzle collections, without guess solving updates:
Code: Select all
With XYZ-Transport ERI Ring examplar 46 added:
