Choosing an Alternative Design for SPOT's Init Task

Many designs generators are available in R. This is one of the main reasons why SPOT is implemented in R. The user can use state of the art design generators for tuning his algorithm. Or, he can write his own design plugin and use it as a plugin for SPOT.

The default SPOT installation contains several design plugins (and further design plugins will be added in forthcoming versions). Table 5 summarizes design plugins from the current SPOT version (0.1.888). The command spotVersion() displays the actual version of your local SPOT package.

A Latin hypercube design was chosen as the default initial design, because it is easy to implement and understand.

These plugins should be considered as templates. They were implemented in order to demonstrate how the interfaces should look like. We strongly recommend an adaptation of these plugins to your specific needs.
