distanceNumericHamming: Hamming Distance for Vectors

In CEGO: Combinatorial Efficient Global Optimization

Hamming Distance for Vectors

Description

The number of unequal elements of two vectors (which may be of unequal length), divided by the number of elements (of the larger vector).

Usage

distanceNumericHamming(x, y)

Arguments

x	first vector
y	second vector

Value

numeric distance value

d(x,y)

, scaled to values between 0 and 1

Examples

#e.g., used for distance between bit strings
x <- c(0,1,0,1,0)
y <- c(1,1,0,0,1)
distanceNumericHamming(x,y)
p <- replicate(10,sample(c(0,1),5,replace=TRUE),simplify=FALSE)
distanceMatrix(p,distanceNumericHamming)
