Description

Chebyshev distance for permutations. Specific to permutations is only the scaling to values of 0 to 1:

d(x,y) = max(|x - y|) / (n-1)

where n is the length of the permutations x and y.

Usage

1

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)
