 | | By modifying key variables, such as the number of moves al lowed each turn, or whether one player can see all of the other's pieces, they are investigating the relative importance of a host of factors that translate to the battlefield, such as numerical superiority, a quick advance and the use of stealth. |
 | | As well as tempo, planning and strength, they looked at stealth (one agent had pieces invisible to its opponent), and the level of "networking" between an agent's pieces (involving the exchange of information on the "value" of the particular move, if any, that each piece could make). |
 | | One important advance from the chess simulations is to allow multiple moves at the same time, as would happen in a battle. |
