This paper is connected with compress-and-forward strategy for two-user relay broadcast channels without common messages, where the relay node has private messages from the source, in addition to aiding traditional communication from the source to the destination.For this terracotta charger channel we derive two achievable rate regions based on the
Under the condition of known static environment and dynamic environment, an improved ant colony optimization is proposed to solve the problem of slow convergence, easily falling into local optimal solution, deadlock premio tab 7 phenomenon and other issues when the ant colony optimization is constructed.Based on the traditional ant colony optimizat
