A Multiobjective Optimization Algorithm to Solve Nonlinear Systems

نویسنده

  • Maria Cristina Recchioni
چکیده

In this paper a computational method to find the solutions of a system of nonlinear equations as the utopia points of a suitable multiobjective optimization problem is proposed. These utopia points are points that minimize/maximize all the objective functions of the multiobjective problem at once. The proposed algorithm finds the utopia points as limit points of trajectories which are solutions of suitable initial value problems for ordinary differential equations. Moreover, it is locally convergent and even works when the number of unknowns is greater than the number of equations. The computational method has been validated on several test problems. A comparison with “fminsearch” Matlab solver has also been carried out. Mathematics Subject Classification: 65K05, 90C29

Multiobjective cuckoo search for design optimization

Many design problems in engineering are typically multiobjective, under complex nonlinear constraints. The algorithms needed to solve multiobjective problems can be significantly different from the methods for single objective optimization. Computing effort and the number of function evaluations may often increase significantly for multiobjective problems. Metaheuristic algorithms start to show...

Solving Nonlinear Equation Systems Using Evolutionary Algorithms

This paper proposes a new perspective for solving systems of nonlinear equations. A system of equations can be viewed as a multiobjective optimization problem: every equation represents an objective function whose goal is to minimize difference between the right and left term of the corresponding equation in the system. We used an evolutionary computation technique to solve the problem obtained...
