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 .
