TOTAL Refactor

Well, I was making lots of new things to my program and it started failing everywhere, so I decided to document all while recheck my code and change lots of things.

This will be hard, but I want my program working good again in some days.

Day 1: Nova era.

Well, I am back. You may think "What happened to the project?", here is my answer:

• Some long conjunctivictis and queractitis took me of the computer for some time
• Lack of time. I had LOTS of things to do lately. 
• Frustration. I was frustrated for all the problems with this. I really needed to stay away from this to get back with new energy and ideas.

Right now I want to get back to the project and this time I will make it work. First I am looking at the code, using Visio to see how it works (is my code and somehow it went out of my hands). At first look I see some things to change, this is the good part of getting out of the project for some time.

So, this is the "Nova Era"

 

Day 158: Back!

Once again, I am back to coding. My eyes are a lot better. Like a month with conjunctivictis, keractitis and all the problems that it gave me... (double vision, couldn't touch my daughter, photofobia, pain) was not something good, now I have to re read some of my code and get back to work.

Day 146: Keratitis -My eyes against me-

The "fun" with my eyes never ends, now that Mr. Conjunctivitis is gone, is time to receive mr. Keractitis and his double vision.

DAMN!

Day 129: Problems with KGS

Ok, the engine works playing using goGui, but not in KGS, I will try to write what happens:

• I connect with my user account Draculinio
• Connect Evil Tesuji using his account on KGS.
• Start a game.
• KGSGTP says something about opponen left the game and returns
• From what I see in my log, some commands are sent, like komi.
• No genmove or play commands sent :(

So, here are my problems... :(

Day 128: The failure after 15D

Well, some good things and some bad things.

Connection worked!

So, I saw Evil Tesuji there:

And almost played:

And then, my little daughter started to cry, and couldn't play the game, then, we went to a birthday party :( But, first thing done. Now, let's try again.

Day 122: This is getting hard

I think I solved some issues, but to get a stable version is another thing. Sometimes ko method is not working at all, I will test it again tonight and make loads of changes. So, the debut will be with 0.01E for now. Suicide seems to be working.

This IS hard.

Day 120: The ship is sinking

This projet is not easy, it never was, but sometimes it gets frustrating. The BIG mistake I made all this time was to test it on 19x19, just to see some moves.

I tested yesterday on 9x9 and found LOTS of problems: Hangs, illegal moves (ko, suicide), problems when the player passes and moves in the border. Most of them are being saved, but it is taking me a lot of work to solve all of this. Well, back to work!

Day 65: L&D I

Let's begin with the most basic thing about Life and Death: Prevention of an atari.

The first approach that I see (I will correct it as long as I think of it) is:

Look at the positions that limit the stone.
If some of them have a stone of the same color, see how many liberties have that group.
If the group have 1 liberty, add that stone and count the liberties again.
If still have 1 liberty quit points, else add points.

This is a very bad approach, but I can evolve from this I think (maybe I am wrong, but... let's try).

NOTE: Ok... while trying this, a wild bug appeared! A suicidal stone was played. Do not know if this happened because the new code ruins all or if there was always that bug.

Day 64: Deadlines & Problems

Sometimes we need deadlines to present something, and I put 15D (december 15th.) as the day that Evil Tesuji will start playing in KGS. I don't think that the program will make a lot and is more to test it. There are some volunteers to test Evil Tesuji from 30 kyu to 5 kyu (I will contact a 4 dan to).
Is obvious that the program will be crushed in every single game, but it can be good as a starting point.

In other notices, yesterday I was trying to test Evil Tesuji against GnuGo, just for fun and to test if the program can end a game (doesn't matter the result). It is really hard. gogui-twogtp didn't work, cgos neither. I will keep working on that.

Day 55: Eureka!

Finaly solved the problem, well, two problems. In suicide the data was persisting somehow, so, inexistent groups were being compared. The other was in how it searched for suicide.

Next: A little video with random moves and a log :).

Day 54: This is getting bad...

All was going good until I saw this:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1
at java.util.ArrayList.elementData(Unknown Source)
at java.util.ArrayList.get(Unknown Source)
at Elements.Board.getMove(Board.java:65)
at Actors.Ruleset.getGroup(Ruleset.java:62)
at Elements.Board.tryToKill(Board.java:80)
at Start.MainLoop.startGame(MainLoop.java:58)
at Start.Principal.main(Principal.java:14)

I think i feel like:

Day 41: Deleting unused code

A lot of things changed when I decided to use GTP. Human class is not needed anymore, so I am deleting it.  I had lots of problems with code, so these days I made some changes, reorganized and fixed some bugs.

I am slow nowadays, raising a baby, working and returning to university having 34 years is hard, but I promise that in 2 days I will be back with more computer go.

Day 20: Problems, problems everywhere...

From the begining I knew this was going to be hard. Now, this is getting harder, I just don't understand what the hell is happening. When I run my program sending manually the command "genmove w" it worked fine, but with gogui, sometimes it sends incorrect data. I am just confused, don't know what is happening, I will try to fix this to continue. I also want to log all what the engine does. I can't use the console for this, I will do it in a file or something...
