RomiChess P3n released

[Michael Sherwin]

Hi Michael.

What I tried was training Romi "bottom-top" instead of "top-bottom".

That is, instead of having Romi play a stronger opponent, she plays a weaker opponent (that she is always able to defeat), and then I increase the strength of the opponent until they're at the same level (i.e. increase the opponent's Depth until Romi draws or loses a game, then Romi trains against the opponent at this depth until she can beat them, and I increase its depth again.)

I was playing Romi at 10 seconds/move against Houdini Typhoon (Tactical=1, Contempt=10) and Romi won all her games up until Depth=7, at Depth=8 the game was drawn.

However, I'm unable to merge this PGN to the learn file, even though I hadn't problems adding 1.2 million games.

Romi just hangs when I try to merge the PGN, can you check it out? Are you able to merge it to a learn file? Am I doing something wrong?

Here's the game I'm unable to merge:

Edited: The pgn will not load into Arena either so there must be something wrong with it. I entered the moves by hand and I thought that there was a problem with 3 fold repetition but I may have entered in too many moves. My eyes are bothering me today so I've done all I can do for now.

I wonder what's wrong with the PGN that not even Arena loads it

I also tried cropping the game up to move 40 to no avail.

I made the moves by hand and had Arena export the pgn to the clipboard.

Arena loads this so I imagine Romi can merge it also.


I did this all with one eye closed and the other eye wants to stay closed so I better call it quits for today. Great idea by the way!

Incredibly, it does not! o_O Romi really hates this game...

Also, I just picked a random PGN with a draw game to investigate, and Romi can't merge it to the learn file, it hangs as well! o_O

Sorry for the question... Maybe i am an idiot ! How can i merge or input a pgn file into Romi's learning file? Thanks for your answer! Thanks Mr Sherwin for this original and interesting engine...

Sorry for the question... Maybe i am an idiot ! How can i merge or input a pgn file into Romi's learning file? Thanks for your answer! Thanks Mr Sherwin for this original and interesting engine...

You have to move the pgn file of the moves you want to merge into the same folder in where the exe resides.

Now, double click Romichess64P3n.exe

A big black box called command prompt appears, you will see this line at the bottom:

White<1>

Now, type:

merge NAME.pgn

Where NAME is the name of the file you want to merge.

For every successful merge, Romi will show a line of text telling you the game number and the Plies of the game. At the end the last game number should match the number of games in the pgn, otherwise Romi failed to import some game(s).

You can also do this by loading the engine in your GUI, and using its Command Line to send commands to the engine (say, in The Shredder GUI, hitting the spacebar allows you to do this), though just double clicking the engine is simpler.

This doesn't appear in any help document, so I also had to ask how to do it, don't feel bad
