I am trying to begin searching for my own spaceships, but I don't really know how to use Gfind. All I found is a text document when I opened what I thought was a download link.

Also, do I need to know C (or any computer language, for that matter) in order to use it? It says it requires platform-independent C, but I am not sure what that means.

If you don't think Gfind is right for me, can you recommend (if there are any) simpler search programs? (dumbed down, if you may?)

Sorry for this question.

Are you using a mac or pc or other? I've had a lot of luck with gfind and afind on the mac, and I could write up a quick list of steps for getting started using those programs on the mac.

Why, yes I am.

Great! I'll write it up as time permits. Maybe we'll see new gunships - maybe even in other rules?

I've been wanting to do gunships in other rules, or perhaps even "hybrid" ships if I get my hands on the proper code to run two rules at once.

I have more conway life battleships at c/3, but I am not sure where to put them.

As for other speeds, I do have some slower and faster ones than c/3, but I don't usually build them due to personal taste. (2c5 and c2 ships can't engage each other except at close distances due to their speed relative to the gliders they shoot, and c4 ships are way too delicate.

Here's a description of how to run gfind on the mac. I'm sorry if the first part is too basic - I don't know what you already know. And more importantly, I'm sorry if the second part is not informative enough -- I'm just a beginner at searching for spaceships. If anyone has any tips, elaborations, or criticism, please share. Platypus5, if the following doesn't get gfind running for you, please let us know. I should also note that I'm using OS 10.6.8 but I've also succesfully gotten gfind running on OS 10.3.9.

Download the latest version of gfind here:
http://www.ics.uci.edu/~eppstein/ca/gfind.c

Place gfind.c in its own folder -- call the folder whatever you want, but for this post, lets call the folder "SearchPrograms".

In your Applications folder, there is a folder called Utillities. Inside Utilities, double click on the program called "Terminal" (or "Terminal.app").

You should see a prompt that looks like this:
YourComputerName:YourUserName$ [cursor]

We're going to use the "cd" command to change the directory to the SearchPrograms folder (folder is just another word for directory).

At the prompt, type "cd " but don't hit enter yet. Note there is a space after "cd". Go to the desktop, drag the "SearchPrograms" folder icon from your desktop onto the terminal program's window, and then click back into the terminal program.

At the prompt, you should see something like this:
YourComputerName:YourUserName$ cd /Users/YourUserName/Documents/CA-stuff/SearchPrograms

This just means we're going to change the directory to the SearchPrograms folder. You could have typed that long file pathway, but dragging it is easier.

Now hit "enter".

You should see something like this at the prompt: YourComputerName:SearchPrograms$

Now we're going to compile the gfind.c program using gcc commmand.

Type this: gcc -o gfind gfind.c
and hit enter.

There will be a pause, there may be some warning messages, and then you'll see the prompt again. Look in the SearchPrograms folder and see if there is now a file called "gfind" alongside "gfind.c". If so, you should be the proud new owner of a spaceship search program. You won't have to use the gcc command again, this was a one time step to convert the gfind.c program into a form your mac can use.

There are two ways to run gfind. The simplest way is to just click on the gfind icon. After you learn more about gfind, you may find it useful to take this shortcut. The shortcut has an annoying drawback -- if you do something wrong, the program quits and you have to start over. One you know what you're doing, this won't matter, but for now, lets stay in terminal program, which is more forgiving while you are experimenting.

Type this at the prompt: ./gfind
and hit enter.

You'll see David Eppstein's prompt for a rule. Lets start with Life.

Type this at the prompt: b3/s23

You'll see a bunch of messages scroll past. Use the scroll bar to look among the messages, and you'll find a few RLEs for some familiar spaceships.

To run gfind again, type ./gfind and hit enter. This time, maybe try a different rule (b36/s23, etc).

Now it is time to learn how to use gfind. Run gfind again, and this time enter "c" instead of a rule. This shows how to add additional information after the rule to specify what kind of search you want to run. The three key commands to get started are o (for orthogonal searches), d (for diagonal searches), and l (for, um, well, in simplest terms, the level of hardness of the search). This last one is particularly important if you want to find anything new. The default level of hardness is 50. If you don't turn up anything interesting, try increasing the level of hardess. Run gfind again, and try it.

I'm going to use b368/s245 as an example, but I confess I haven't run the following searches recently - it might not be the most interesting example.

Typing in b368/s245/ does a shallow search for spaceships in that rule.
b368/s245/l60 does a more exhaustive search.
b368/s245/l70 does a more exhaustive search still.
The searches start to get really slow for some lnn, where nn is between 80 and 100. Searches start to take hours, and as nn grows, they take days. This isn't necessarily unreasonable -- I believe some people on this forum have run searches that take months. But if you're less patient than that, don't worry! Specificying a specific speed and direction allows the program to prune the search space so that we can search big nn's.

b368/s245/o4 searches for orthogonal ships with period 4 at default level 50.
b368/s245/o4/l60 does the same search at level 60, which is more exhaustive.
b368/s245/o4/l70 is even more exhaustive still.
and so on. For any given length of time, you'll be able to search larger lnn's than if you didn't specify what speed and direction you were looking for.
Substitute "d" for "o" for diagonal searches, eg b368/s245/d7/l60.

You can further prune the searches (and thus allow lnn to get bigger) by studying the list gfind prints out when you enter "c" instead of a rule. Note that you can string together as many search specification as you like, separating them by slashes. You might want to look at the comments at the begining of the gfind.c file (use a text editor or word processor). And of course, you can read Eppstein's paper, "Searching for Spaceships": http://arxiv.org/abs/cs.AI/0004003

For new search sessions, start the termnial program. Change the director to SearchPrograms as described above, and then type ./gfind. Alternatively, just double click on the gfind icon in your SearchPrograms folder.

Note that many of the easiest searches have already been done. As you know, you can find these results at David Eppstein's website. However, Eppstein's lists aren't meant to be exhaustive, and for more obscure rules, even easy searcehs turn up interesting stuff not listed by Eppstein. For example, my favorite B0 rule is B013468/S02 and I found new spaceships at l80 for c/8, and at c/4 and c/6 for l110 and l125 respectively. (I've been meaning to post about this rule!)

Let me know if this post gets you running. If it does, I'll write up afind. Gfind is the right place to start, but given your particular goals, I think you'll like afind even better! (It generates more c/2 and c/3 ships than you'll ever be able to use, and it does it lightning fast!)

Thanks, but for some reason, I can't seem to compile gfind. It says "bash:gcc command not found"

I am going to try to look it up on my own, but do you have any idea what I am doing wrong?

D'oh! I just realized what the problem is. You'll need to install the stuff for developers. A DVD came with your mac that has stuff for developers. I'm pretty sure installing xcode will give you gcc, but that might be overkill. Still, if you have room on your hard drive, the quickest solution might be to pop in the DVD, follow the prompts to install xcode , and then try the steps in my post again.

If "pop in the developers DVD and install xcode" does not suffice as useful advice, this link might be helpful:

thanks! After some work, I got it functioning. Now, I just need to figure out the command syntax.

Thank you!

Sorry to bump a really old topic, but this seemed the best place to post this.

When I run a search using gfind, the output only gives (at most) one ship for each period/speed, and often it's not even of the full period (eg. it will output a c/2 p2 ship when searching speed 3c/6). When I search B3/S2456/o5 with /l70 it finds a 13 cell wide ship, but trying the search again with /l80 it finds a wider, shorter ship but doesn't output the 13-cell one.
Is there any way to stop this from happening, and to allow the software to output all (or at least more) ships for each speed?

Posted: **June 5th, 2015, 6:40 am**

The parameter "f" controls how many spaceships gfind will output before terminating. So, /f100 will output 100 ships, assuming there are that many to be found in the first place.

Oh, no. AFAIK getch is a Windows specific function... I'm not sure if anyone has tried to run it on Linux?
EDIT: and so is _cprintf... (You can google it and find out that it is from conio.h, a Windows-specific header.)

Final update: See http://clang.llvm.org/compatibility.html#inline. Removing the inline keyword is a reasonable choice. A perhaps better choice is changing "inline" to "static inline". Problem solved.

Original post and earlier updates:
Any success with these recent problems? I get fewer errors than the above, that's the good news:

Further update: Removing the "inline" keyword on the definitions of the mentioned functions gets rid of the errors and gfind seems to run without errors — though how much it slows things down not to have those functions explicitly inline I don't know.

Look at the powder toy.

Don't know if this is the right thread, but how does one search for knightships and preview partial results with gfind-pt (I can't seem to decipher the inbuilt descriptions)?

FYI, I'm not going to use this for life, I was going to use it to search for knightships in non-totalistic rules.

Simply include the /k command with the parameters. For example, "gfind-pt B3/S23/o6/n2/l120/k" will search for a width-10 (2,1)c/6 knightship.

Goldtiger997 wrote:how does one... preview partial results with gfind-pt

To preview partial results, you need to use the /p ("dump state") command at the start of the search. After each deepening step a file should be produced with the name "dumpNNNN" where "NNNN" is some number. To view the partial results in that file, run "gfind-pt p dumpNNNN > output.txt".
