Functions

func CheckError

func CheckError(e error)

func Exchange2Nodes

func Exchange2Nodes(data []int, i, j int)

func GenerateRandomPermutation

func GenerateRandomPermutation(n int) []int

	 Copyright (C) 2004  Thomas Stuetzle
      FUNCTION:       generate a random permutation of the integers 0 .. n-1
      INPUT:          length of the array
      OUTPUT:         pointer to the random permutation
      (SIDE)EFFECTS:  the array holding the random permutation is allocated in this
                      function. Don't forget to free again the memory!
      COMMENTS:       only needed by the local search procedures
