Write LP File for Polyomino Problem

**POLYOMINO_LP_WRITE**,
a MATLAB program which
writes an LP file describing a (binary) integer programming problem
related to the tiling of a region R by copies of polyomino
shapes, with possible reflections and rotations.

LP files are a simple file format, used for linear programming problems and related cases. They can be read by programs such as CPLEX, GUROBI, and SCIP.

**polyomino_lp_write** is available in
a MATLAB version.

- polyomino_lp_write.m, writes an LP file describing a particular problem.
- polyomino_monohedral_example_reid_system.m, returns the linear system associated with a polyomino tiling problem.
- timestamp.m, prints the current YMDHMS date as a timestamp.
