Author: Daniel Mehrmann (Germany) Released: 2007-07-29Link: Homepage
This is the most annoying engine I've seen so far. 1. The only way to install this engine is to run the installer, which creates an unneeded start menu folder, adds an uninstall entry, and who knows what else. 2. If you try to remove some of its files, or move it to a different folder, it doesn't work anymore, reporting a failed copy protection check. It's a freeware, so what the heck? 3. Under Vista it insists on using "C:\Users\Username\AppData\Roaming\HomerChess" directory for ini file, log file, learning file, etc., instead of the same directory where it is installed. 4. Even if you set "Learning = off" in the ini file, it still defaults its UCI "Learning" option to "On". 5. Even if you set "Learning" UCI option to "Off" too, it still uses the "learn.dat" file. It reads the entire file when it starts, in writes the entire file back to disk when it quits. Fortunately it's possible to disable this by making "learn.dat" read-only. 6. It actually talks, sometimes saying "Hello" and "Good night". Try running an automated engine-engine match (blitz TC) and listen to music at the same time! Fortunately deleting the .wav files helps.
This engine is stable and runs without issues.
This is the only Homer version we tested.

This figure shows how this engine performs depending on how strong is the opponent. Regression:

Perf = C − 0.006 [±0.327] * Opp

Where 'Opp' is the opponent's rating. 95% confidence intervals are in the brackets.
