encodepop: Binary encoding of real number matrix

In adana: Adaptive Nature-Inspired Algorithms for Hybrid Genetic Optimization

Binary encoding of real number matrix

Description

The encodepop function generates a population encoded with binary representation from a real-valued population given as a matrix.

Usage

encodepop(x, lb, ub, eps, ...)

Arguments

x	A vector containing real numbers
lb	A vector containing lower bounds for variables
ub	A vector containing upper bounds for variables
eps	Sensitivity vector containing desired sensitivity values for each variable
...	Further arguments passed to or from other methods.

Value

binmat	A binary coded matrix as counterpart of real-valued input matrix
m	A vector containing bit length of each variable

Examples

lb = c(2.5, -2, 0)
ub = c(4.3, 2, 1.5)
eps = c(0.1, 1, 0.01)
#d = nchar(sub('^+','',sub("\.",'',eps)))-1
d = grep('.', strsplit(as.character(eps), '')[[1]])-1
x = round(runif(5, lb[1],ub[1]),d[1])
y = round(runif(5, lb[2],ub[2]),d[2])
w = round(runif(5, lb[3],ub[3]),d[3])
pop = cbind(x, y, w)
pop
encpop = encodepop(pop, lb, ub, eps)
head(encpop$binmat[,1:10])
m = encpop$m
