As tactical warfare continues to accelerate with ever-greater complexity, battlefield commanders must increasingly deal with larger and larger data bases generated under dynamic situations. Typically, this data solicits time critical decision having far reaching consequences. This situation results from the unpredictable nature of modern warfare, and the tremendous increase in communications, computational, speed and memory capabilities. Today's technical community now face serious challenges to exploit new and evolving technologies. Digital networks appear promising as a decision aid in such areas as pattern recognition and classification, signal processing and robotics. One specific requirement is to develop new techniques for terrain analysis. Phase I demonstrated that a genetic algorithm could be used to train DPLM networks to perform low-level reasoning to recognize potential approach avenues for standard terrain data bases like the Tactical Terrain Data (TTD) base. This was then regulated by a payoff function which defined the total network performance. Phase II proposes development of a reasoning system for determining approach avenues by combining the low level feature recognition and using the genetic algorithm to train digital networks with a higher level reasoning concept. Tasks include development of a hardware system to operate on the TTD for demonstration.
