myBWID employs evolutionary algorithms for the identification of Bouc-Wen hysteretic systems.

Viscous damping can also be identified based on suitable experiments. The program implements a new hybrid evolutionary algorithm which is based on gradual decrease of the allowable domain of model parameters.
