Renamed `ioccc.ico` to `favicon.ico`. Correctly added use of `favicon.ico` to all constructed HTML headers. Fixed the smart quote in HTML elements problem. Moved HTML "DO NOT EDIT" comments down below at the bottom of the HTML phase 1 section. According to to the Nu Html Checker, a charset attribute on a meta element found after the first 1024 bytes. Changed `bin/md2html.sh` VERSION from "1.1.3 2024-03-28" to "1.2 2024-03-30". Improved `bin/gen-status.sh` to adjust the "status_update" value only when the "contest_status" is changed. Performed a `make www` to perform and test the above under macOS.

|
||
<p>By default, the number of colors is 6. You may specify a
|
||
value of between 1 and 15 colors. See the author’s notes
|
||
for instructions of how to play.</p>
|
||
<p>We look forward to more entries from the newer members of the
|
||
International Internet community.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This program plays
|
||
[Mastermind](https://en.wikipedia.org/wiki/Mastermind_(board_game), if you call
|
||
it by a name ending by ‘d’, otherwise it <em>solves</em> Mastermind. Call it without
|
||
parameters to use 6 digits (colors), or indicate the number of possible digits
|
||
(you cannot change the number of positions so easily).</p>
|
||
<p>The number in parentheses is the number of possible combinations,
|
||
based on previous questions and answers. If you solve the puzzle,
|
||
“(1)” indicates that your previous moves are enough to give correct
|
||
answer. If the program acts as solver and terminates prematurely,
|
||
it means that you’re mistaken in your answers to its question(s).
|
||
Question marks indicate the number of digits you have to enter
|
||
(either 4 when you guess or 2 when computer guesses).</p>
|
||
<p>Note that the program uses the same code for both player and
|
||
solver, and the only place where it makes a difference is the
|
||
interactive part. Many obfuscations have been made to achieve
|
||
this. An expression giving <code>(bulls * 16 + cows)</code> from two numbers
|
||
is, however, quite straightforward :-) , as well as the arithmetic
|
||
of binary coded colors-base numbers is.</p>
|
||
<h3 id="limitations-maximum-number-of-digits-colors-is-14-1..f.">Limitations: maximum number of digits (colors) is 14 (1..F).</h3>
|
||
<p>Suggestions: Use terminal (or emulator) with non-destructive
|
||
backspaces. Do “disable scrolling” on cmdtool or similar emulators.</p>
