[Help-glpk] Re: Sudoku - can anyone make this work?

[Martin]

Thanks to Andrew the small bug in my code has been corrected. However, 
rather than obtaining a solution in 42 seconds I ran glpsol for about 2 
hours before terminating with no solution. The last few lines of output are 
listed below. What's happening?

Thank you.
