Verson 1.0-exp9 has been released. It adds two new "helper" classes ComplexMove and ComplexTabuList to aid in cases where multiple attributes are being tracked in the tabu list.

OpenTS is a java tabu search framework that helps you implement the popular tabu search meta-heuristic in a well-defined, object-oriented design. Among the key advantages of this framework:

• Works with any problem type. You can solve vehicle routing problems, assignment problems, or your favorite packing problem. OpenTS makes no assumptions about the type of problem you may solve.
• Offloads repetitive tabu search functions. You can define your problem and your ideal tabu search and leave the grunt work to OpenTS.
• Logically organizes your tabu search. You can better explain and understand your tabu search when it follows the well-structured design of the OpenTS framework.
• Exploits modern computer technology. You can take advantage of object-oriented programming and the cross-platform Java language including the ability to use multi-processor computers and deliver applications over the Internet.
• Integrates goal programming. You can evaluate solutions in more than one dimension and compare solutions first by comparing the most important value, then the second, the third and so on.
