sFFLHD-class {sFFLHD}

sFFLHD object that gives a batch of points at a time.

Description

sFFLHD object that gives a batch of points at a time.

Value

A sFFLHD object

Fields

D

numeric. The number of dimensions for the design. Must be set.

L

numeric. The number of points in each batch, also the number of levels of each dimension. Must be set.

maximin

logical. Should maximin distance be used to space out points? TRUE by default. Only used while lb <= 100, not worth it once the boxes are very small.

a

numeric. A root of L that determines the intermediate stages. Is automatically set to smallest possible value, which is recommended.

b

integer. The batch number.

nb

integer. The number of points selected so far.

lb

numeric. Current levels of the small grid.

Lb

numeric. Current levels of the intermediate grid.

Xb

matrix. Current design matrix, continuous from 0 to 1.

Vb

matrix. Small grid design.

Mb

matrix. Intermediate grid design.

Wb

matrix. Big grid design.

A1

matrix. The first OA slice.

r

integer. Used to keep track of loop index.

p

integer. Used to keep track of loop index.

Ar

matrix. Current Ar.

stage

integer. Current stage.

vii

integer. Used to keep track of location in stage 2.

Fslices

list. A list of slices.

FF1.1

matrix. Temporary matrix used to generate slices.

Mb.store

matrix. Temporary storage of Mb.

v.shuffle

integer. A storage value for storing order. Requires extra optimization.

Examples

s <- sFFLHD$new(D=2,L=3)
s$get.batch()
s <- sFFLHD$new(D=2,L=4)
s$get.batch()
