Knight's Trip
(c) 1997, Gheorghe SAVULESCU
Welcome to "Knight's Trip" !
One of the most popular logic puzzles is the covering of the
checkerboard using the knight. Put the knight somewhere on the classic
(8x8) checkerboard, then start moving it to pass once and only once
through each field on the board. While the problem is well known,
I have found no attempts to solve this or a similar problem in a more
general way.
"Knight's Trip" solves the problem for all rectangular boards,
everything being presented in an easy to follow hypertext form with
plenty of graphics. For each board size, the text presents a specific
solution, shows how to build a solution using solutions for smaller
boards, or proves that no solution exists.
In fact, this file solves two variants of this puzzle: it may be
required or not that, after passing through all squares of the board,
the knight jumps back to the starting field and closes the path.
"Knight's Trip" is a Windows Help format file. Version 3.10 of WinHelp
is the minimum requirement, but special provisions have been made to
give a 'Windows 95' look for those who use this operating system.
Disclaimer
Users of "Knight's Trip" must accept this disclaimer of warranty:

This directory must exist. Long filenames are not supported.
The installation program will only unpack the necessary files. It does

About Shareware. Registration
"Knight's Trip" is shareware - the "try before you buy" distribution
method. You are free to evaluate it for 30 days from the initial
installation, after which you must either register or delete the
software from your system. You are encouraged to pass a copy of the
self-installing archive KNIGHT10.EXE, in an unmodified form, to your
friends for evaluation. Please encourage them to register their copy
if they find it interesting.
If you find "Knight's Trip" interesting, please register. After
registering, you will NOT get a disk with another version, because the
shareware version is complete, but:
- You may legally continue using "Knight's Trip";
- The registration extends to any future version of this product;
when you find a newer version of "Knight's Trip", just download
it - no other registration fee is required;
- You will have the satisfaction of supporting the Shareware concept.
Currently, I do not have a computer of my own, so developing "Knight's
Trip" was very (even excessively) long and difficult. Only with help
from users, taking the form of registration, I can get the things I
need for developing other shareware products.
The registration fee is 5 to 10 U.S. dollars (USD), or an equivalent
amount in one of the following currencies (the list is long, so I
quote only the monetary symbols): ATS, AUD, BEF, CAD, CHF, DEM, DKK,
EGP, ESP, FIM, FRF, GBP, GRD, IEP, ITL, JPY, NLG, NOK, PTE, SEK.
There are two ways to get the money to me. In order of (my) preference:
- Simply send banknotes;
Warning: generally, the post makes no warranties for values,
including money, enclosed in letters.
- Send a postal money-order.
Sorry, no credit cards. Sorry again, no checks.
Send the money, together with your name and address, to:
Gheorghe SAVULESCU
str Valea Calugareasca 3, ap 63
77472 Bucharest 6
ROMANIA
Thanks in advance for your support!
Distributing "Knight's Trip"
Permission is granted to distribute copies of "Knight's Trip" subject
to the following conditions:
- Distribute the self-installing archive KNIGHT10.EXE, and not
separate components.
- The file's contents should not be modified in any way. The whole
file may be compressed with a standard packer in order to use
less space on the distribution media or to decrease download time.
Please name the archive "KNIGHT10.ext", where "ext" is the
extension normally associated to the file packer used.
(Note: I do not think the size reduction will be significant,
10% at most.)
- It is not incorporated in another hardware or software product (but
may be distributed on disks or CDs along with other shareware).
It should be clear for the user that this is a stand-alone
shareware product.
- Distribution is either free of charge, or only a modest copying and
distribution fee, to cover media and handling, is charged. It should
be clear for the user that the amount charged, if any, is for the
service of copying and distributing, and not for buying or licensing
the contained shareware product.
If you decide to compress the file, and your distribution site allowes
users to examine online some files in the archives (the "README"-like
files, for example), please include this README.TXT file along
with KNIGHT10.EXE.
