These are the context codes that I am currently testing. I'm using the terms context-AMAF (CAMAF) and context RAVE (CRAVE). 10 bits: case 0: printf("context %d: eye creating \n", k); break; 0: printf("context %d: eye creating \n", k); break; case 1: printf("context %d: pat \n", k); break; 1: printf("context %d: pat \n", k); break; case 2: printf("context %d: self_atari \n", k); break; 2: printf("context %d: self_atari \n", k); break; case 3: printf("context %d: capture \n", k); break; 3: printf("context %d: capture \n", k); break; case 4: printf("context %d: enemy-atari \n", k); break; 4: printf("context %d: enemy-atari \n", k); break; case 5: printf("context %d: ladder-like attack \n", k); break; 5: printf("context %d: ladder-like attack \n", k); break; case 6: printf("context %d: rescue \n", k); break; 6: printf("context %d: rescue \n", k); break; case 7: printf("context %d: liberties_for_move == 2 \n", k); break; 7: printf("context %d: liberties_for_move == 2 \n", k); break; case 8: printf("context %d: running \n", k); break; 8: printf("context %d: running \n", k); break; case 9: printf("context %d: squeeze \n", k); break; 9: printf("context %d: squeeze \n", k); break; default: printf("context %d: NO CONTEXT \n", k); break; : printf("context %d: NO CONTEXT \n", k); break; case 1, matching a pattern, is a binary flag indicating that the move makes any "good" 3x3 pattern. case 4, ladder-like attack, means that it puts a foe group into atari, that group couldn't gain a liberty by capturing, and couldn't gain > 2 liberties by moving onto its single liberty. case 8, running, means it gives a friendly group >= 3 liberties where it had 2 liberties before. case 9, squeeze, means it reduces a foe group to 2 liberties (but they might be eyes...). If ladder testing is enabled, there is an 11th bit for that result. I'm certain that this is not the ideal set of features. I'd be very interested in what the group thinks they should be. - Dave Hillis
