Use of evolutionary methods for bioeconomic optimization models: an application to ®sheries
نویسندگان
چکیده
Bioeconomic optimization models are regularly used in ®sheries policy analysis. However, the use of these models has been restricted in ®sheries, as in other similar ®elds, where there are a large number of non-linear interactions. In this paper, the basic features, advantages and disadvantages of the use of the evolutionary methods, speci®cally genetic algorithms, are discussed. A large non-linear model of the UK component of the English Channel ®sheries is developed using genetic algorithms. The results are compared with those from a linearized version of the model solved using traditional optimization techniques. The results suggest that genetic algorithms may provide better solutions for large non-linear bioeconomic models that cannot be solved using traditional techniques without the use of simplifying assumptions. # 2000 Elsevier Science Ltd.

متن کاملRelational Databases Query Optimization using Hybrid Evolutionary Algorithm
Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...

متن کاملVerification of an Evolutionary-based Wavelet Neural Network Model for Nonlinear Function Approximation
Nonlinear function approximation is one of the most important tasks in system analysis and identification. Several models have been presented to achieve an accurate approximation on nonlinear mathematics functions. However, the majority of the models are specific to certain problems and systems. In this paper, an evolutionary-based wavelet neural network model is proposed for structure definiti...
