At the start, the PM is:
- Code: Select all
124 245 9 8 13 46 236 256 7
128 6 178 13 5 79 238 4 389

5 347 367 236 238 1 9 27 48
169 8 167 256 4 569 27 3 15
149 349 2 7 389 589 48 15 6
And the thermo constraint amounts to setting r5c3=5 OR r4c4 ≠ 4
First trying to solve with r5c3=5 gives a trivial solution (with Singles):
- Code: Select all
459816327
261357849
378492165
726183594
915264783
834975612
543621978
687549231

Trying to solve with r4c4≠4 also gives a trivial solution (with Singles):
- Code: Select all
459816327
261357849
378492165
726183594
915264783
834975612
543621978
687549231
192738456
Miracle: the two solutions are the same.
