Original Abstract
The paper presented deals with a methology of optimization the design rainfalls for the needs of urban drainage by means of Genetic Algorithms (GA). The new approach is based on processing tens real rainfalls from historical series of rain data in the form of a catalogue which will consist of several categories of characteristic rains. By characteristic rain we understand the rain of time- dependent varying intensity that gives a true picture of the rainfall events in the area under investigation.A rainfall are very difficult to solve by mathematical programming approaches. A genetic algorithm (GA) is an extremely powerful optimization technique that could be used to solve such problems, but its efficiency is dependent on its ability to do a large number of evaluations in a reasonable amount of time. A classical GA contains three basic operators - reproduction, crossover, and mutation. To increase the efficiency of a genetic algorithm the influence of migration in a multilevel distributed GA (MDGA) was tested. Several different structures of PC-computers connected in a local area network (LAN) were used for the MDGAs. MDGAs use the power of the computers better than one-level distributed GAs. The problem of communication between the computers in the MDGAs was dealt with in two different ways: with files on a server or by sending packets. Our approach is the development of hybrid learning algorithms by integrating genetic algorithms with neural learning algorithms. The development of representation GA for neural network architecture is major problem in future. Our approach is the development of hybrid learning algorithms by integrating genetic algorithms with fuzzy neural learning algorithms.
