The script in this directory creates wordcross diagrams: rectangles containing a set of words that are all rookwise connected to each other but aren't adjacent to each other unless they cross.
One example of a wordcross puzzle is the "Presidential Rectangle", explored by a series of articles over a few decades in Word Ways:
- We must all hang together
- A Presidential Rectangle
- A New Presidential Rectangle
- A Smaller Presidential Rectangle
- An Improved Presidential Rectangle
- The Ultimate Presidential Rectangle?
This directory has a file numbers.txt with the numbers ZERO through TEN. You can generate
all 8-by-8 wordcrosses containing these numbers by running create-wordcross.sh numbers.txt 8 8,
which should generate rectangles like:
...F..F.
ZERO.SIX
.I.U..V.
.G.R.TEN
.H...H.I
.TWO.R.N
...N.E.E
..SEVEN.
..FIVE..
TWO..I..
..U..G..
ZERO.H..
...N.TEN
SEVEN..I
I......N
X..THREE
Unfortunately, the presidential rectangle is a bit too challenging for the solvers in this repo for any recent list of presidents.
