hydroPSO

hydroPSO is a global optimisation R package implementing a state-of-the-art version of the Particle Swarm Optimisation (PSO) algorithm (SPSO-2011 and SPSO-2007 capable), with a special focus on the calibration of environmental models.

hydroPSO is parallel-capable, to alleviate the computational burden of complex models.

hydroPSO is model-independent, allowing the user to easily interface any model code with the calibration engine (PSO), and includes a series of controlling options and PSO variants to fine-tune the performance of the optimisation engine. An advanced sensitivity analysis function together with user-friendly plotting summaries facilitate the interpretation and assessment of the calibration results.

Bugs / comments / questions / collaboration of any kind are very welcomed.

Installation

Installing the latest stable version from CRAN:

install.packages("hydroPSO")

Alternatively, you can also try the under-development version from Github:

if (!require(devtools)) install.packages("devtools")
library(devtools)
install_github("hzambran/hydroPSO")

Reporting bugs, requesting new features

If you find an error in some function, or want to report a typo in the documentation, or to request a new feature (and wish it be implemented :) you can do it here

Vignettes

1. Here you can find a vignette showing how to use hydroPSO to calibrate parameters of the GR4J hydrological model, which belongs to the airGR family of models.

2. Here you can find a vignette showing how to use hydroPSO to calibrate parameters of TUWmodel.

3. Here you can find a vignette showing how to use hydroPSO to calibrate parameters of SWAT-2005 and MODFLOW-2005.A similar approach can be used to calibrate SWAT-2012 or other models that need to be run from the system console.
