Description

Workhorse for correctSigns

Usage

getSignCorrection(r, A1, C1, eps, A2, C2, epsvec, flip, swap, w, swapIsOneFlip,
  maxActions, maxCombinations)

Arguments

r

The numerical record to correct

A1

Equality matrix

C1

Constant vector for equalities

eps

Tolerance for equality-checking

A2

Inequality matrix

C2

Constant vector for inequalities

epsvec

Vector to check against. (.Machine.double.eps for > inequalities, otherwise 0.)

flip

indices in r, where r may be sign-flipped

swap

n\times2 matrix with indices in r, each row indicating a possible value swap.

w

weight vector of length(flips)+nrow(swaps) if swapIsOneFlip==TRUE, otherwise of length(r)

swapIsOneFlip

logical. If TRUE, weights are assigned to each flip or swap action. If FALSE weights are assigned to every changed variable.

maxActions

Maximum number of flips+swaps to try.

maxCombinations

the maximum number of flip/swap combinations to try. See the description in correctSigns

Value

a list containing

S	n x length(r) array with corrected versions of r
weight	vector of length n with total weight for each solution
nFlip	number of sign flips for every solution
nSwap	number of value swaps for every solution
