I am trying to do some simple gmpl model but as a complete beginner I noticed I
cannot do it.
THe issue appears not to be representing a model in GMPL,
but getting a model to represent.
col1 col2 col3
row1 x
row2 x x
row3 x x x
Assign numbers 1..6 to the x cells so that every number has different row and
col than the previous number.
I suggest 2 2D arrays of binary values.
xincol[x, c] == 1 iff x in column c.
xinrow[x, r] == 1 iff x in row r.
Constraints are left as an exercise for the reader.
