summary
This exception is for defence of player. In this sample engine is first (X) player and his top "flag" value is 1000. Second player (O) have "three" structure (NNOOONN), consequently two squares with "flag" value bigger than best "flag" value of first player. Shortly second (O) player has two better moves than first (X) player. But if one of them is on the same square position with the best move of first (X) player, he have effective defence. If engine detect such common square in "flag" arrays, increase value in his "flag" array (here "flagx") on value 9999 (higher than best value of second player).
More about "three" structure: see previous page.
The same sample as above-mentioned, but without "three" structure.
Next exception for defence. Only for engine as second (O) player. Best values for both players in their "flag" arrays is 100, and one of them has common square position. If engine detect such common square in "flag" arrays, increase value on this position in "flago" array (9999).
In this sample have second (O) player higher "flag" value (200) than first player (100).
Condition for exception here so is not perform.
Last exception for defence. Only for engine as second (O) player. First (X) player have "three" structure and: maximum "flagx" value of first player is 5000 and maximum "flago" value of second (O) player is lower than 2000. Therefore in "flagx" array must exist two (more) squares with maximum (5000) value ("three" structure"), better is square with higher value on the same position in the araray "flago". On this position increase "flagx" value on 9999. If also both values in array "flago" they are identical (for example: 0, 0), increase both values in "flagx" array" (9999, 9999).
Search top values in arrays "flagx" and "flago":
//int xmax = 0; //flagx: maximum value //int omao = 0; //flago: maximum value //int xmax_o = 0; //maximum flagx value: maximum flago value on the same square //int omax_x = 0; //maximum flago value: maximum flagx value on the same squareSearch crossmix exception. If yes, change values in "flag" arrays:
for(row = 0; row < rcmax; row++) { for(column = 0; column < rcmax; column++) { if(xmax < flagx[row][column]) xmax = flagx[row][column], xmax_o = flago[row][column]; if((xmax == flagx[row][column]) && (xmax_o < flago[row][column])) { xmax_o = flago[row][column]; } if(omax < flago[row][column]) omax = flago[row][column], omax_x = flagx[row][column]; if((omax == flago[row][column]) && (omax_x < flagx[row][column])) { omax_x = flagx[row][column]; } } }
