heuristic model
3.A heuristic algorithm for solving the model mentioned above was proposed the advantages of which were lower demand for initial values of decision variables; lower storage and less CPU time for computations and relative deviation of less than 1 % in comparison with the results of using mathematical programming software (MINOS 5.0).
4.OPTI system (Optimizing System of Network Data Model Structure) constructs for a data base designer a network data model which satisfys some requirements for a set of objective variables by employing a man-machine interactive and heuristic process with interactive successive refinement, and produces automatically the DDL and DMCL source programs, which describes the model.
6.The heuristic information and the multiplex nonlinear optimization were combined to configure the structure of fuzzy model, and the input data space was partitioned into some local regions based on entropy clusting and competitive learning algorithm, and then the T-S model for thermal process was built with weighted recursive least-square algorithm (WRLSA).
7.A heuristic search algorithm has been put forward for the 0-1 goal programming model by establishing optimal evaluation function,and by using the state-space theory of Artificial Intelligence. Moreover,a software system has been developed by using C language to solve the 0-1 goal programming model,which is very difficulty to realize as yet by computer.
