The auxiliary class AgentProblem is an extended data structure which initially contains the decision problem (i.e. a MIP(Mixed Integer Problems) ) of an agent which is passed to the OsiSolverInterface to be solved. Finally the MIPs solution should be passed back from the OsiSolverInterface to the agent by the MipHandler using the class AgentSolution. The Interface between AgentF and OsiSolverInterface (meassage handling) is the class MipHandler. The structure and contents of this class corresponds essentially to the structure and contents of an mtx file. An mtx file is identical to the first part of a (new)dat file.
