Hi all,
I want to use tabu search to solve my minimization problem. but tabu
search in R is for maximization, so I turn my function from f to -f， but the
eUtilityKeep always be 0 from the second position. I have go through a part of
source code found that it always give the default value to compare,
move <- ifelse(maxTaboo > maxNontaboo & maxTaboo > aspiration,
ifelse(length(which(neighboursEUtility == maxTaboo))
== 1,
which(neighboursEUtility == maxTaboo),
sample(which(neighboursEUtility == maxTaboo), 1)),
ifelse(length(which(neighboursEUtility == maxNontaboo
& tabuList == 0)) == 1,
which(neighboursEUtility == maxNontaboo &
tabuList == 0), sample(which(neighboursEUtility == maxNontaboo & tabuList ==
0), 1)))
this cause the 0 value.
How can I use it to get my minimization value using tabu search in R ?
Thanks .
