1. A method for feedback control of cooperative problem solving for real-time applications in complex systems, wherein the method utilizes a plurality of solvers parameterized by control variables, the method comprising:

  • initializing the time setting;

    selecting not less than one solver parameter value, such that expected solution quality is optimal;

    operating the solver with said not less than one selected solver parameter value for a specified interim;

    reviewing solver operational conditions, wherein said operational conditions include a performance measure, comprising the difference between expected performance and actual performance, and solution quality;

    transmitting a solution to the system if said solution quality condition is satisfied;

    continuing to operate the solver with said not less than one selected solver parameter value if said solution quality condition is not satisfied and said difference between expected performance and said actual performance is not above a specified threshold;

    selecting not less than one alternate solver parameter value if said solution quality condition is not satisfied and said difference between expected performance and said actual performance is above a specified threshold;

    operating the solver with said not less than one alternate solver parameter value for a specified interim; and

    continuing to operate the solver with said not less than one alternate solver parameter values until said solution quality condition is satisfied.
