I independently came up with a similar, yet somewhat simpler, algorithm for use in my next version of non-totalistic apgsearch, v0.3i, to possibly replace pseudo_bangbang(). My modification is to consider off cells that are overcrowded as interacting as well as on cells, similar to the current vers...

The step 'find the smallest number of other components' is ill-defined. It could be that there's a spaceship A which survives if either B or C or both are present, but not when B and C are simultaneously absent. If you're not that interested in speed, then you can consider all partitions of the con...

A while ago I announced that I was working on some cool CA-related project. This is indeed the case, and the ultimate goal of this project is to create an up-to-date online interactive database of spaceships in lifelike CA. It is now in the earliest stage of development: actually, I haven't started ...

What about the synthesis of 30P4H2V0.4 ? It was mentioned in the 2015 pattern-of-the-year list, but technically was only completed in 2016. It's an impressive-looking example of Kazyan-style synthesis, and unlike last year we don't have a lot of other new spaceship recipes to compete with it (do we...

It is included with the copperhead.

Even though most people agree that 2016 was a terrible year overall , it was certainly quite a good year for the Game of Life. Many discoveries were made, and it is only logical to select the coolest one of them by organizing yet another Pattern of the Year competition. As usual, we start by compili...

muzik wrote:So is pattern of the year 2016 coming up?

Yeah, it will probably go live today.

Saka wrote:Alexey, can you make wsearch for this.

It is quite a non-trivial task, and I will not volunteer to do it. If someone wants to give it a try, I can publish Delphi source code.

Spaceships are impossible in this rule, since no pattern can grow out of its bounding diamond.

Happy birthday to 2017! I will start the Pattern of the Year 2016 competition soon.

I am missing something..... ....if C1 soup search is run for apgsearch on 16x16 soups... that is 256 cells per soup..... with 2 states that is 2^256 soups..... ...while we're nowhere close to that number..it is somewhat possible that some are repeated at some point.... ....does apgsearch use both i...

Some context or explanation would be greatly appreciated.

I think there is nothing wrong with your username.

Probably useless:

I know we can get 50%, can we get higher?

Code: Select all

x = 12, y = 12, rule = B3/S23:T12,12
12o2$12o2$12o2$12o2$12o2$12o!

No.

Instead of posting screenshots, please do the following: Select the entire pattern in Golly. Copy it. Go to the forums. Paste. Select the code you pasted. Press "Code" above the editor. You should get something like this: x = 16, y = 5, rule = B3/S23 2b2o3b2o3b2o$bo2bobo2bobo2bo$obobob4obobobo$bo2bo...

I don't think this is the right name.

#C Stabilizes in 2 generations x = 4, y = 1, rule = B3/S23 4o! I think the rules should be more specific. Firstly, limit the bounding box to 20x20 or something. Otherwise one could post a long diagonal line. Limiting the number of cells is not an option, since one could post a glider hitting a fara...

"what spaceship produce switch engine?"

Text like that probably comes from a Markov chain trained on other posts on the forum. Markov chains rarely produce full grammatically correct sentences, so this is one way to recognise them.

Gamedziner, you surely wrote a great message, but I think spambots do not deserve that much attention. I can give you one nontrivial tip on recognising spambots: look whether their messages could be posted on a completely different forum and still seem pretty relevant. For example, "This is a great ...

Hmm, that looks like a fun game. Here is my challenge:
