In the low level,the coalition formation algorithms based on the ant colony optimization(ACO) ,the particle swarm and ant colomy optimization(PSACO) ,or the quantum-inspised ant colony optimization(QACO) was proposed respectively for performin a tight-coupled task.Simulations were performed and results showed that PSACO provides the best solution,but its running time is the largest;QACO is a little inferior in solution quality to PSACO,however,it needs only a half time of the 2 other methods.
