wfgEvalAndWrapUtil: Utility functions for wfgEval and wfgWrap

In tudob/wfg: WFG toolkit implementation package

Description

used only within wfgEval
checkTrafoComplete: different transformations can be applied throughout the vector - this can be done multiple times, each time the vector wraps around (from last index to first) - the last transformation overall has to end at the last entry of the vector, this function checks that condition.
checkShapeComplete: similar to checkTrafoComplete (however shapes dont wrap around).
tToX: transformations are applied to the search-space vector, shapes to the objective-space vector. tToX does the transformation of the first to the second and also integrates the degeneracy factor A.

Usage

wfgEvalAndWrapUtil()

checkTrafoComplete(target.index)

checkShapeComplete(target.index, current.shape)

tToX(t, M, A)

Arguments

target.index	checkTrafoComplete and checkShapeComplete decide based on target.index and current.shape whether the transformation/shape is complete.
current.shape	see target.index
t	Search-space vector used in the t-to-x transition
M	Objective-space dimension
A	Degeneration constant
