Or perhaps just use a language that's designed to solve those sorts of problems? In 14 lines of code.

cenamus•3w ago
Is there a similarly short/simple solution not using all of the built ins? Haven't worked with prolog in a while but should be easy enough with primitives (albeit with more duplication)?
crustycoder•3w ago
Well no, not really. The whole point is to use the appropriate tool for the task at hand. In this case it's the CLP(FD) library, https://www.swi-prolog.org/pldoc/man?section=clpfd

Why not just

    blocks(Rows, Blocks), maplist(all_distinct, Blocks), maplist(label, Rows)

Peter Seibel's original post is worth reading in its entirety.

It's a decently balanced piece. It leaves room for various views, and its summation seems about right.

I remember implementing some of these

https://www.stolaf.edu/people/hansonr/sudoku/12rules.htm

With a simple array of unsigned int and bit operations like 20 years ago. It could solve a lot of puzzles within microseconds. Later I realized rules 1, 2, 5, 6 are pretty much the same.
