---------------
|

|

This class supports global optimization algorithms (particle swarm, dual annealing, evolutionary algorithms) for finding an optimal set of relaxation times that minimise the error between the actual and the approximated electric permittivity, and calculates optimised weights for the given relaxation times.
|

Code written here is mainly based on external libraries, like ```scipy``` and ```pyswarm```.
