hydroPSO: a new R package for model calibration
Mauricio Zambrano-Bigiarini
I would like to draw your attention to hydroPSO, a newly developed R
package for the calibration of (complex) environmental models.
hydroPSO implements a state-of-the-art Particle Swarm Optimisation
(PSO) algorithm, which is a global optimisation technique with a surge
of attention given its flexibility, ease of implementation and
efficiency.
Key features of hydroPSO are:
1) Model-independent calibration engine
2) Platform-independent (GNU/Linux, Windows, Mac OS X)
3) Minimal user intervention to define I/O functions for interfacing
hydroPSO with the model code
4) Several fine-tuning options to customise the calibration engine
(for advanced PSO users)
5) Sensitivity analysis included, using the Latin Hypercube
One-factor-At-a-Time (LH-OAT)
6) Several functions for post-processing of the calibration results
hydroPSO and its user manual are already available on CRAN:
http://cran.r-project.org/web/packages/hydroPSO/
you can install it with:
> install.packages("hydroPSO")
This package includes a vignette (tutorial) showing how to calibrate
SWAT-2005 (http://swatmodel.tamu.edu/software/swat-model/) for
real-world case studies.
You can download the vignette and all the files required to follow the
two case studies from:
http://www.rforge.net/hydroPSO/
