#LHD 1.1.0 This is a big update for the whole package.

Part I - We added the following three optimality criteria:

Average absolute correlation (function name: AvgAbsCor)

Maximum absolute correlation (function name: MaxAbsCor)

Maximum projection criterion (function name: MaxProCriterion)

Part II - We updated the following functions:

SA, OA2LHD, OASA, SA2008, SLHD, LaPSO, GA

In the past, only maximin distance LHDs can be generated through these algorithms. Now, the default optimality criterion is the set to be “phi_p” still, which corresponds the maximin distance, but these algorithms are able to generate orthogonal LHDs and maximum projection LHDs, respectively.

Another modification is that the majority of input arguments now have default settings. For those seeking instant design matrix or quick search, simply input run sizes and factor sizes would be enough. This modification saves times for users.

Part III - The DESCRIPTION file, documentations (.Rd files), vignettes, and test files were updated accordingly.

#LHD 0.1.3 Updated SLHD function: The exchanging logic in Stage II has been updated.

#LHD 0.1.2

The following functions have been updated:

SA, OASA, SA2008, SLHD, GA, and LaPSO.

The default for p used to be 50, and now is set to be 15. Besides, modifications were made for each function above to improve accuracy of result. Correspondingly, documentations (.Rd files), vignettes, and test files were updated. These updates should also fix the errors from the CRAN Package Check Results.

#LHD 0.1.1

The Description field of DESCRIPTION file has been updated.
