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 ?
