Group AI (Defense-based Strategy)

When one robot is in danger, its teammates should consider providing support.

ASI (Ally Safety Index) = ∑ (allyMass / reachTime)HSI (Hide Safety Index) = selfMass / reachTime

ETI (Enemy Threat Index) =∑ (enemyMass / reachTime) BTI (Border Threat Index) = 1 / reachTime

TSI (Total Safety Index) = ASI + HSI - ETI - BTI

Group AI

When one robot is in danger, its teammates should consider providing support.

Path Risk (teammate) = ∑ (enemyMass / reachTime)Gain (teammate) = TSI (seek) - TSI (current)

for all Gain(robot) > 0 dowhile(ally still in danger) doGainMAX(robot) -> go guard the one in danger
