Least Squares Fitting of Chacón-Gielis Curves by the Particle Swarm Method of Optimization

Mishra, SK - Volkswirtschaftliche Fakultät, … - 2006

Ricardo Chacón generalized Johan Gielis's superformula by introducing elliptic functions in place of trigonometric functions. In this paper an attempt has been made to fit the Chacón-Gielis curves (modified by various functions) to simulated data by the least squares principle. Estimation has...

escape from being caught in such local optima. The Particle Swarm Method of global optimization is one of such methods. A … immediate neighbours and the ideal performers. The Particle Swarm method of optimization mimics this behaviour. Every individual … to each other and adjust their own position and velocity based on these good positions. The Particle Swarm method of …

Some new test functions for global optimization and performance of repulsive particle swarm method

Mishra, Sudhanshu - Volkswirtschaftliche Fakultät, … - 2006

In this paper we introduce some new test functions to assess the performance of global optimization methods. These functions have been selected partly because several of them are aesthetically appealing and partly because a few of them are really difficult to optimize, while all the functions...
