Abstract:
GARP (Genetic Algorithm for Rule-set Production) is an extension of the
BIOCLIM approach
which aims to develop models with:
- all forms of environmental data, including climate and soils data
- arbitrary distributions, including bi-modal (two peaked)
- concise rules using few variables
Genetic algorithms are general purpose optimization techniques based on biological principles.
GARP (Genetic Algorithm for Rule-set Production) uses a genetic algorithm to automate the use
of environmental data collected through field surveys to produce distribution maps and models.
This method has been largely applied to predicting the distribution of species of animals and
plants but can potentially predict any observable environmental entity. The method has a number
of benefits:
- quantitative determination of probabilities on any data, including presence-only (eg.
museum) records,
- value adding to sparse survey data by increasing coverage and resolution,
- automated production of images, maps and documentation,
- production of easily comprehended models based on rules for explaining relationships in
the data.
