10.  2004, G.Tecuci, Learning Agents Center 10 President Roosevelt is a strategic COG candidate that can be eliminated Test whether President Roosevelt has the critical capability to be protected Test whether President Roosevelt has the critical capability to stay informed Test whether President Roosevelt has the critical capability to communicate President Roosevelt has the critical capability to communicate through executive orders, through military orders, and through the Mass Media of US 1943. These communication means have no significant vulnerabilities Test whether President Roosevelt has the critical capability to have support Test whether President Roosevelt has the critical capability to be a driving force Test whether President Roosevelt has the critical capability to be influential Test whether President Roosevelt is a viable strategic COG candidate Does President Roosevelt have all the necessary critical capabilities? No. The necessary critical capabilities are: be protected, stay informed, communicate, be influential, be a driving force, have support and be irreplaceable Which are the critical capabilities that President Roosevelt should have to be a COG candidate? Test whether President Roosevelt has the critical capability to be irreplaceable President Roosevelt has the critical capability to be protected. President Roosevelt is protected by US Service 1943 which has no significant vulnerability President Roosevelt has the critical capability to stay informed. President Roosevelt receives essential intelligence from intelligence agencies which have no significant vulnerability President Roosevelt has the critical capability to be influential because he is the head of the government of US 1943, the commander in chief of the military of US 1943, and is a trusted leader who can use the Mass Media of US 1943. These influence means have no significant vulnerabilities. President Roosevelt has the critical capability to have support because he is the head of a democratic government with a history of good decisions, a trusted commander in chief of the military, and the people are willing to make sacrifices for unconditional surrender of European Axis. The means to secure continuous support have no significant vulnerability. President Roosevelt has the critical capability to be a driving force. The main reason for President Roosevelt to pursue the goal of unconditional surrender of European Axis is “preventing separate peace by the members of the Allied Forces”. Also, “the western democratic values” provides President Roosevelt with determination to persevere in this goal. There is no significant vulnerability in the reason and determination. President Roosevelt does not have the critical capability to be irreplaceable. US 1943 would maintain the goal of unconditional surrender of European Axis irrespective of its leader because “the goal was established and the country was committed to it”. There is no significant vulnerability resulted from the replacement of President Roosevelt COG example

16.  2004, G.Tecuci, Learning Agents Center 16 Team assignment: Preliminary modeling Perform a preliminary modeling of the problem solving process, corresponding to the assigned sub-domain of the PhD Advisor selection. Start with the task “Assess John Doe with respect to ” as illustrated on slide #6. Model only the task reduction part of the tree (as shown on slides #6, 7, 8) but go down up to elementary solutions (see remark on slide # 9), and be as complete as your example allows (That is, each question has only one answer, the one corresponding to the person you are considering, as indicated below). We will perform the modeling for solution synthesis latter. To perform the modeling, consider a specific person as the potential PhD Advisor to assess, and a specific area (e.g. Intelligent Agents) or student, so that all your steps refer to these objects. You may have in mind a real person (in which case you will not reveal his name beyond your team) or an imaginary person. Your team will have up to 30 minutes to discuss the modeling with the class. Arrange such that each member of the team makes part of the presentation. Due date: October 12 th, 2004
