Skybuck is back with a new programming contest oh yeah ! ;) :)
For this programming contest the mission is as follows:
A bitmap has to be "convexified" which means the following:
Convex polygons have to be made which describe the boundaries of the red
pixels of the bitmap.
The polygons must be convex.
Each pixel of the bitmap can be considered a box.
This means the pixel's coordinate is actually turned into two x coordinates
0 and 1.
The pixel shares these coordinates with it's neighbours.
So a simply polygon for a single pixel would look like:
The order of the points can be clock-wise or counter-clock-wise.
The goal is to keep the number of convex polygons as low as possible.
The goal is also to keep the number of edges as low as possible.
I am not yet sure which goal should get priority. Maybe goal1 automatically
leads to goal2, or perhaps not.
To get this contest started the same bitmap as the "BoxifyMe" contest will
The output and thus the entries for this contest should look as follows:
X, Y (starting point)
X, Y (starting point one more time to indicate it's closed.)
X, Y ( starting point of second polygon )
X, Y ( starting point of second polygon again to indicate it's closed. )
Good luck and may the convex polygons have mercy on your soul ! ;)
Entries can be sent to skybu...@hotmail.com
The best entry will become the King of the Contest.
Will you be sitting in this chair ?
See website ;) :)
This is your chance to become a King ! ;) :) Even if it's only for a few
seconds, minutes or days ! ;) :)
Hurry up and get that code cracking some output ! ;) :)
Entries/solutions will be made publicly available for further study and
analysis to make sure it's valid.
Overlapping convex polygons are allowed. Though non-overlapping polygon
entries are also welcomed.
I will also be entering the contest.
Goodbye, for now,
So I might consider changing the competition a little bit to make it
possible to simply submit a "pixel based" polygon" instead of a "boundary
However first I would need to make sure that I have a "pixel" to "boundary"
polygon converter to make sure that this is indeed possible.
So stay tuned for more details coming in the next days/weeks/months.
Christmas and New year is coming up so I understand it might be a busy weak
for some folks out there... with all this family related stuff going on...
so these contests will run for a long time... maybe even forever...
I can understand if people enter later on in january or so ;) :)
If you do want to enter early make sure you state what type the
input/output/entry is either:
1. Boundary based.
2. Pixel based.
Skybuck ;) :)
