The first of several qualification rounds is over. Below you can see the results of a one second-per-move qualification round played from both sides of the second position in the Silversuite opening lines (games available on the tournament page). The first 15 engines proceed to the final qualification round. Congratulations to all chess engines authors.

In this case especially Lucas. After my Android adventures, I still intend to go back to BikJump and improve my own engine, and your rise to fame is an inspiration. Respect!!

MinkoChess 1.3 and Texel 1.01 will nicely fill the huge elo gap between Critter 1.2 and the rest. Note that MinkoChess 1.3 is an SMP engine, you just need to set the relevant UCI option (IIRC it's called "SMP" or "Threads").

One second-per-move qualification round (2d group) played from both sides of the second position in the Silversuite opening lines (games available at the tournament site). The first 15 engines proceed to the final qualification round, where 30 engines (and perhaps one mystery guest!) will face off for placement in groups A to F.

Hi Aart,

Is there a reason why you are using myrddin0.85j instead of 0.86 ?

Jim.

Unfortunately texel 1.01 contains a bug that will get it stuck in an infinite CPU eating loop if stdin is closed without the engine first receiving a quit command. I don't know if this will happen when run in chess for android, but it did happen to me when testing it in droidfish, at least during droidfish development when I installed new droidfish versions using eclipse.

The fix is simple:

Code: Select all

--- src/uciprotocol.cpp (revision 57)
+++ src/uciprotocol.cpp (revision 58)
@@ -48,7 +48,10 @@
     if (autoStart)
         handleCommand("uci", os);
     std::string line;
-    while (getline(is, line) >= 0) {
+    while (true) {
+        getline(is, line);
+        if (!is || is.eof())
+            break;
         handleCommand(line, os);
         if (quit)
             break;

The hard part is recompiling the source code.
