Rush Hour 'Traffic Jam' Solver is a C++ application that reads a Rush Hour board from a text file, solves it, and produces a nice PostScript file that shows the shortest solution. So you can cheat when you can't solve the problem yourself.
Unpack the tarball archive
tar xzvpf rush_hour-*-src.tar.gz
Switch to the new directory
build the program
It will materialise as ./rush_hour.
In the directory where rush_hour was created, and where the file level.txt or level32.txt is found, invoke
It will produce a solution for level 32 and store the result in solution32.ps. You can look at that now:
Or print it:
Level File Format
For level number X, you can store the level in either the file level|X|.txt or in the generic file level.txt.
Look at level32.txt. It reads:
This is a comment
This is also a comment.
The 32: is the level number. There must be a level number even in the special file named after the level it containts. A level body contains the board setup. The following characters are used:
a,...,k length-2 cars
o,...,r length-3 cars
x, y, z your own cars
. empty board cell
After the board cells are defined, there may be an optional comment, starting with line starting with a minus characters. After the optional comment, the board definition is terminated by an empty line.
There may be several boards in one file, each in the format described above.
Currently, the board has a fixed size of 6x6 cells. This can be changed in the source code, but it is untested.
