Attitude determination with navigation satellites is a key technology in aviation, marine and land navigation. In the method based on carrier phase difference, the double difference integer ambiguity solving is important and difficult. This paper adopts Discrete Particle Swarm Optimization to search for the optimal integer ambiguity directly without the decorrelation of ambiguity, and calculates the...
Cooperating and sharing resources by creating coalitions of agents are important ways for autonomous agents to execute tasks and to maximize their payoff. However coalition formation is a complex process which usually causes a mass of computation and communication. In this paper, we focus on situations where time is limited and coalitions may be formed as soon as possible. To address this problem,...
