distancePermutationSwapInv {CEGO}

Inverse-Swap-Distance for Permutations

Description

The swap distance on the inverse of permutations x and y. See distancePermutationSwap for non-inversed version.

Usage

distancePermutationSwapInv(x, y)

Arguments

x

first permutation (integer vector)

y

second permutation (integer vector)

Value

numeric distance value

d(x,y)

, scaled to values between 0 and 1 (based on the maximum possible distance between two permutations)

Examples

x <- 1:5
y <- c(1,2,3,5,4)
distancePermutationSwapInv(x,y)
p <- replicate(10,sample(1:5),simplify=FALSE)
distanceMatrix(p,distancePermutationSwapInv)
