POLYOMINO_MULTIHEDRAL_TILING_PLOT
Plot Solutions of Polyomino Multihedral Tiling
POLYOMINO_MULTIHEDRAL_TILING_PLOT,
a MATLAB library which
is given matrices defining a region R and a set of polyominoes P,
and a vector X, computed by POLYOMINO_MULTIHEDRAL, which represent a
tiling of R by the polyominoes in P. The task is to
plot a representation of that tiling.
The problem being solved is discussed in the documentation for
POLYOMINO_MULTIHEDRAL. Briefly, a region R is to be tiled by one or
more copies of polyominoes stored in P. The solution procedure treats
as "variables" all distinct rotation, reflections, and translations of
the polyominoes that fit exactly onto some portion of R. The solution
is a binary list that indicates a selection of these variables that
tile R completely.
This function takes the solution vector of selected variables, such as:
1 0 1 0 1 0 0 1 0 0
and produces a plot of the corresponding tiling of the region,
which might be:
1 1
8 3 3
8 5 3
