Roll back ad04d21fda
As was discussed with Landon this was a mistake even if it helped with
consistency. There was even a brilliant pun that was destroyed with that
commit which I think is worth pointing out:
cp README.md hill
./ant hill
in 1991/ant ... even if it's technically 'anthill'.
I hope that I got all links fixed in years.html and winners.html. As
well I tried to make sure I got all handles fixed in all/summary.txt.
Nevertheless these should be checked. For some handles they were never
updated (at least in the html files - though maybe summary.txt too, not
sure) in the first place so there was nothing to do.
Typo fixes like references to *.hint when it should be README.md. There
probably are others that need to be fixed but haven't been located yet.

# Regarding individual entries:
|

#
|

# IOCCC winning entry code may not work on your system. Even with standards,
|
||||
# conditions and build environments change, especially when it comes to more
|
||||
# extreme code such you might find in an IOCCC winner. Moreover, what was
|
||||
# allowed and liked in one IOCCC contest may no longer be liked/allowed in
|
||||
# later IOCCC years.
|
||||
#
|
||||
# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
|
||||
#
|
||||
# GitHub pull requests are welcome:
|
||||
#
|
||||
# If you have a patch that might make running an entry work in modern Unix-like
|
||||
# environments, please create a GitHub pull request for the IOCCC judges to
|

# consider.
|

#
|

# Suggestions and corrections regarding Makefiles, winning author information,

# fixing typos in remarks, and code patches are welcome via opening a GitHub

|
||||
## To build:
|
||||
|
||||
make all
|
||||
|
||||
NOTE: thanks to Yusuke Endoh for the pointing out that `atof()` nowadays needs
|
||||
`#include <stdlib.h>` in order to get this to work. Thanks also to Cody Boone
|
||||
Ferguson for fixing some segfaults under modern (and in some cases earlier)
|
||||
systems with this entry.
|
||||
|
||||
|
||||
## To run:
|
||||
|
||||
./mariano expression x1 x2 h y1
|
||||
|
||||
where:
|
||||
|
||||
expression - function f(x,y) (see below)
|
||||
x1 - start of interval
|
||||
x2 - end of interval
|
||||
h - step size
|
||||
y1 - initial value (y(x1) == y1)
|
||||
|
||||
|
||||
## Try:
|
||||
|
||||
./mariano y 0 1 0.1 1
|
||||
|
||||
|
||||
|
||||
## Judges' comments:
|
||||
|
||||
The program's source implements four functions, all from the
|
||||
same source file!
|
||||
|
||||
When you compile mariano.c as is and run with 5 args, it numerically
|
||||
solves the equation y'=f(x,y), with a step size of h, over the interval
|
||||
x=[x1,x2], with the initial condition of y(x1)=y1.
|
||||
|
||||
The 'expression' f(x,y), is any function of 'x' and 'y' with the
|
||||
operators:
|
||||
|
||||
+ - * / ^
|
||||
|
||||
The symbol '^' is the power operator. Note that it only supports
|
||||
integer powers. Also note that all expressions are evaluated strictly
|
||||
left to right. (i.e., parenthesis aren't supported).
|
||||
|
||||
Try running the program with the following args:
|
||||
|
||||
./mariano y 0 1 0.1 1
|
||||
./mariano 1/x 1 2 0.1 0
|
||||
./mariano 'x^2/y+x' 0 1 0.1 6
|
||||
|
||||
But wait, there is more! You also get, free of charge, a
|
||||
reversing filter! Try:
|
||||
|
||||
./mariano -r 0 0 0 0 < mariano.c > sorter.c
|
||||
|
||||
Still not impressed? The author throws in for free, a
|
||||
sort program! Try:
|
||||
|
||||
cc sorter.c -o sorter
|
||||
ls | ./sorter
|
||||
|
||||
This program is safe for home use as well. The author has
|
||||
included a safety feature in case you misplace the original
|
||||
program source:
|
||||
|
||||
./sorter -r 0 0 0 0 < sorter.c > mariano_bkp.c
|
||||
|
||||
And finally, as a special offer to users of this entry,
|
||||
the author provides a Fibonacci sequence generator! Try:
|
||||
|
||||
./sorter 0 0 0 0 < mariano.c > fibonacci.c
|
||||
cc fibonacci.c -o fibonacci
|
||||
./fibonacci 1 1
|
||||
./fibonacci 2 1
|
||||
|
||||
Program available 9 track and cartridge cassette. Gensu knife
|
||||
not included! :-)
|
||||
|
||||
When this program was first shown at the 1990 Summer Usenix
|
||||
conference, it received a standing ovation; a first for
|
||||
a contest entry.
|
||||
|
||||
Originally we noted that the 4 trailing args '0 0 0 0' were required on systems
|
||||
that dump core when NULL is dereferenced but this problem showed itself in
|
||||
modern systems even with the 4 '0 0 0 0'. To make this easier for users Cody
|
||||
Boone Ferguson kindly fixed this problem.
|
||||
|
||||
|
||||
## Author's comments
|
||||
|
||||
Differential equations are solved via the Runge-Kutta method,
|
||||
which guarantees local error proportional to h^5, and total
|
||||
error across a finite interval is at most a constant times h^4.
|
||||
|
||||
Sorting is accomplished with a standard shell sort.
|
||||
|
||||
Note that the sorting and reversing is limited to files with
|
||||
fewer than 500 lines, each less than 99 characters long.
