Day 57: First video and log

As I promised, here is a video of how is the program working so far.

The program is SLOW, this is because I am logging a lot, it is running on an overcharged computer and is running from a pendrive. So, to save this I should:

1. Make less logging (just log the same info but writing less).
2. Sometimes I should run this from a computer that works well, it just plays random moves, it shouldn't take so long to choose a valid move.
3. Run it from a hard disk XD.

But, right now what bothers me is how to continue.

The log (10 moves... 206kb.), that is something impossible to keep.

Day 29: Suicidal rule

Until now I was filtering possible moves by two things:

• Spaces with a 0 (Empty)
• There is no Ko

But, there are other spaces that could be not allowed to be played, let's see suicidal rule:

Here is the definition in Senseis

In most common ruleset, suicide is forbidden, so for now it will be for my program (maybe some day I will do something for the other rulesets).

So, there is how I will implement it:

1. The number of liberties of the group if I play this move == 0?
2. If not, move is allowed
3. if yes, try to kill groups of the other color.
4. If kills, move is allowed
5. if not, this is a suicide move and can't be played.

I just created a method to see if a move is suicide (this is my first aproach, not tested yet):

public boolean isSuicide(Board board,int move, int color){ boolean suicide=false; ArrayList<integer> group = new ArrayList<>(); ArrayList<integer> liberties = new ArrayList<>(); int killedStones=0; board.setMove(move, color); if(color==1){ killedStones=board.tryToKill(2); }else{ killedStones=board.tryToKill(1); } //If there are no killed stones if(killedStones==0){ group=this.getGroup(move, board); liberties=this.getLiberties(group, board); //If no liberties found, then it is suicide. if(liberties.isEmpty()){ suicide=true; } } return suicide; }

Maybe tomorrow I will continue coding, or today if I have some time (I wish I can). 

Day 26: Logging

To see if all what I want to control on the engine is working the way I like, I need to log all that it does. This is the first approach to this:

Important: In Windows 7 you need to run GoGui in Administrator Mode.

I made methods to:

1. Log any String I want.
2. Log the date and time
3. Log the board as it is in the moment.

  public class ETLog { private File myFile; public void log(String text){ myFile=new File("G:\\EvilTesuji\\ETLOG.TXT"); myFile.setWritable(true); try { if(!myFile.exists()){ try { myFile.createNewFile(); } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } FileWriter fr=new FileWriter(myFile.getName(),true); try (BufferedWriter bw = new BufferedWriter(fr)) { bw.write(text+"\r\n"); bw.close(); } } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } public void logDate(){ DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); Date date = new Date(); myFile=new File("G:\\EvilTesuji\\ETLOG.TXT"); myFile.setWritable(true); try { if(!myFile.exists()){ try { myFile.createNewFile(); } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } FileWriter fr=new FileWriter(myFile.getName(),true); BufferedWriter bw=new BufferedWriter(fr); bw.write(dateFormat.format(date)+"\n"); bw.close(); } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } public void logBoard(Board board,int size){ int i,j; int pointer=0; //pointer to know the place in the arraylist. String line=""; ArrayList<integer> b=new ArrayList<>(); b=board.getMainBoard(); myFile=new File("G:\\EvilTesuji\\ETLOG.TXT"); myFile.setWritable(true); try { if(!myFile.exists()){ try { myFile.createNewFile(); } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } FileWriter fr=new FileWriter(myFile.getName(),true); BufferedWriter bw=new BufferedWriter(fr); for(i=0;i<size+2;i++){ for(j=0;j<=size;j++){ switch(b.get(pointer)){ case 0: line=line+"0"; break; case 1: line=line+"B"; break; case 2: line=line+"W"; break; case 3: line=line+"#"; break; } pointer++; } line=line+"#"; //putting the right border bw.write(line+"\n"); line=""; } bw.close(); } catch (IOException ex) { Logger.getLogger(ETLog.class.getName()).log(Level.SEVERE, null, ex); } } }

I have to make some changes but the basic idea works. Now I can delete console class and replace it with this.
