Abstract:: The basic ant colony algorithm tended to be trapped in local optimum in solving task scheduling problems of cloud computing.A probability adaptive ant colony optimization was proposed.This algorithm rankd the tasks in descending order according to their size,defines the task concentration degree,and introduces the probability adaptive adjustment factor to adjust the assignment probability of over-concentrated resource noded.The results showed that the proposed algorithm shortened the task completion time,and had some improvements on convergence speed,compared with the Ant Colony Optimization and Modified Ant Colony Optimization.
