1. A knowledge processing system comprising:

  • a memory for storing knowledge in a plurality of knowledge modules in a knowledge bank, the knowledge including data associated with preexisting solutions to previous problems; and

    a processing unit for receiving sensory signals from an external device, the sensory signals including problem-related data corresponding to a current problem, the processing unit operating knowledge-based software and including;

    a knowledge processing unit for generating a plurality of artificial intelligence based modules by processing the current problem using a natural language processor to generate tentative code, and for executing the plurality of artificial intelligence based modules to process the input signals representing data, including problem related data corresponding to the current problem, for generating a plurality of solution-related modules from the data representing the pre-existing solutions, with the solution-related modules corresponding to solutions to the current problem;

    a numerical processing unit for generating a confidence level associated with a respective solution to the current problem by applying the tentative code to the current problem and generating, the confidence level from a tentative solution corresponding to the tentative code; and

    a database processing unit for controlling the storing of the solution-related modules in the memory;

    wherein the knowledge processing unit, responsive to the confidence levels of the solutions, iteratively revises the solutions to generate an optimal solution to the current problem by determining a solution strategy using the confidence level corresponding to the tentative solution and adjusting the solution strategy to increase corresponding confidence levels the optimal solution being transmitted as data signals to at least one device.
