A number of tuning approaches for PID controllers are considered in the context of intelligent tuning methods. However, in the case of a 2-DOF PID controller, tuning based on classical approaches such a trial and error has been suggested. A general view is also provided that they are the special cases of either the linear model or the single control system. On the other hand, since the immune network system possesses a self organizing and distributed memory, it is thus adaptive to its external environment and allows a PDP (parallel distributed processing) network to complete patterns against the environmental situation. It can also provide an optimal solution. Simulation results reveal that immune algorithm based tuning is an effective approach to search for optimal or near optimal control.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.

This paper extends the tree representation of GP to evolve multiple comprehensible IF-THEN classification rules. We introduce a concept mapping technique for the fitness evaluation of individuals. A covering algorithm that employs an artificial immune system-like memory vector is utilized to produce multiple rules as well as to remove redundant rules. The proposed GP classifier is validated on nine benchmark data sets, and the simulation results confirm the viability and effectiveness of the GP approach for solving data mining problems in a wide spectrum of application domains.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.

This allows the net to exploit salient regions (both within and across sources) of what may otherwise be an unwieldy input domain. Small recurrent neural networks are evolved to perform object detection within airborne reconnaissance imagery that has been processed to provide 3 colour bands and 2 feature maps including one designed to identify man-made structures based on perpendicularity of edge direction. A variable input field is shown to provide faster convergence and superior detector fitness over a number of trials than a set of alternative fixed input field mappings.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.

On a problem with known premature convergence behaviour, the MAX problem, similarity replacement significantly decreased the rate of premature convergence over the best that could be achieved by manipulation of the mutation rate. The expected CPU time for a successful run was increased due to the additional cost of the similarity matching. On a problem which has a very expensive fitness function, the evolution of a team of soccer playing programs, the degree of premature convergence rate was also significantly reduced. However, in this case the expected time for a successful run was significantly decreased indicating that similarity replacement can be worthwhile for problems with expensive evaluation functions. A significant discovery from our experimental work is that a small change to the way mutation is carried out can result in significant reductions in premature convergence.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.
