@LeonidShifrin - Your answers to whatever question are worth re-reading! I wished that you made time for a new edition of your mathematica programming book. But perhaps you moved on, to other challenging stuff.

I have this message on Windows 10. Probably related to out of memory.

comment How to select a submatrix containing similar elements from a matrix?
Also: This ( I referred to it in the question ) mathematica.stackexchange.com/questions/50578/… has a solution that comes very, very close and is compact.

Thank you, - Knuth allegedly said that optimization comes last. This is a start! Please read the comment section about what @ciao said about the problem. I will work on this again this evening UTC+1.

@ciao - The thing is that the answer in the related question comes awfully close! And that is only a Mma one-liner. - I will get back on this, later.

@Ciao I got a copy of the book. Will read it tomorrow, I assume you mean the Chapter on Two Dimensional Matching, right?

@ciao I am working on the route as described in the related question. I would be happy with a hint in the right direction. I only post questions here after serious attempts. Don't know where you live, but it is almost bedtime won't be able to work on it for 18 hours.

That was a good question @glance. I added it to the original question above.

Second example could be a 1x3 with 1s and a 1x2 with 1s. Leaving the 1 in the final matrix would not be correct.

comment How to select a submatrix containing similar elements from a matrix?
It does not really matter as long as no doubles remain in the final matrix. So regarding the first a 4x3 with 1s and a 2x2 and a 2x2 with 2swith 1s is ok but also a 2x5 with 1s and a 2x3 with 1s and a 2x2 with 2s is ok.

Entirely new function to me. I will look into it. Thanks.

There is a conflict in the example. Report both. Report horizontal and vertical.
