However, as the example at the top in Two-factor Latin Hypercube Design shows, the Latin Hypercube design does not necessarily do a great job of space filling. This is a two-factor Latin Hypercube with 16 runs, with the factor level settings set between -1 and 1. Note that this design appears to leave a hole in the bottom right of the overlay plot.

Two-Factor Maximum Entropy Design
Technical Maximum Entropy designs maximize the Shannon information (Shewry and Wynn (1987)) of an experiment, assuming that the data come from a normal (m, s2 R) distribution, where
is the correlation of response values at two different design points, xi and xj. Computationally, these designs maximize |R|, the determinant of the correlation matrix of the sample. When xi and xj are far apart, then Rij approaches zero. When xi and xj are close together, then Rij is near one.
