I present a schema that can be used to build, manipulate, and
inspect a constraint matrix.
A possible class which can be used, as an instance of a GLPK
contraint matrix, to solve the represented problem is presented.
Details including the SQL needed to create the database, and a
simpler example are available at:
http://www.geocities.com/nigel_galloway/Sqlite3_GLPK.pdf
Attached is KuKu.Sqlite3.rb which is the class; solve.rb which is a
possible use of the class; and miniSudoku.test1.sqlite3 which is
the database.
ruby solve.rb miniSudoku.test1.sqlite3 should generate the solution.
It requires NigelzGLPK details of which can be found at
