- On april 5 the doldrums eased .
- The firewall has gone through 5 generations and the current main stream is firewall with state inspection
- In order to handle the subgraph isomorphism problem , the concept of individuals with state backtracking was proposed , where the state information of some potential individuals produced during the evolution were preserved , which contributed to the design of genetic operators
- The thesis designed the structure of a firewall in global , and then it go deep into the problem of searching and maintaining the filter rules and the state inspection table . it employed the data structure and algorithms of geometry and graph theory in the design of firewall
- Finally the decision - making subsystem gives the output velocity of both wheels of the robot , and the real - time control is realized . on studying the robocup ' s decision - making subsystem of distributed control mode , it discusses the environment of the simulator match , the architecture of soccerserver and its work mechanism in details , which is very significant to theory research , including the important parameters of soccerserver , communication between soccerserver and clients , visual - audio and physical information of agents , etc . then it uses a client program to demonstrate the process of communication and how the sending command worked
