The DiGGer search uses a randomisation of all possible treatment plot
interchanges to find an improvement to the current design in the
search. If no improvement is found after all interchanges have been
tested the searchIntensity
defines the percentage of
interchanges to consider for a non-improving move. Low search
intensities are useful for finding optimal designs with a single block
factor.
