WolframRule30 {PPRL}

Apply Wolframs rule 30 on bit vectors

Description

Apply Wolframs Cellular Automaton rule 30 on the input bit vectors.

Usage

WolframRule30(ID, data, lenBloom, t)

Arguments

ID

IDs as character vector.

data

character vector containing bit vectors.

lenBloom

length of Bloom filters.

t

indicates how often rule 30 is to be used.

Value

Returns a character vector with new bit vectors after rule 30 has been applied t times.

Examples

# Load test data
testFile <- file.path(path.package("PPRL"), "extdata/testdata.csv")
testData <- read.csv(testFile, head = FALSE, sep = "\t",
  colClasses = "character")

# Create bit vector e.g. by CreateCLK or CreateBF
CLK <- CreateCLK(ID = testData$V1,
  data = testData[, c(2, 3, 7, 8)],
  k = 20, padding = c(0, 0, 1, 1),
  q = c(1, 1, 2, 2), l = 1000,
  password = c("HUh4q", "lkjg", "klh", "Klk5"))

# Apply rule 30 once
res <- WolframRule30(CLK$ID, CLK$CLK, lenBloom = 1000, t = 1)
