The knapsack problem (KP) is a typical NP- complete problem. In this paper, a novel tabu search (TS) algorithm with the elite set is presented to solve the KPs. The algorithm is a hybrid TS with a binary differential operator (BDO), which is denoted by TSBDO. The binary differential operator is employed to mutate individuals which are generated randomly from the list EliteSol. To validate the prop...Show More
In this paper, Hybrid Tabu Search (TS) and Particle Swarm Optimization (PSO) is proposed to generate Fuzzy Controller with only three rules. The algorithm dynamically adjusts the membership functions and fuzzy rules according to different environments. At each iteration of PSO algorithm, we calculate the best solution and we seek the best neighbor by Tabu search, this operation minimizes the numbe...Show More
In distributed systems, the server placement problem in which a new server has to compete with existing servers for user requests is important in planning of constructing new business service sites. In addition to minimizing cost, competition-aware server placement also needs to maximize the benefit of building a new server. This paper proposes a Tabu Search approach to optimize the problem in gen...Show More
This paper aims to discuss and compare various metaheuristic algorithms applied to the “Knapsack Problem”. The Knapsack Problem is a combinatorial optimization maximization problem which requires to find the number of each weighted item to be included in a hypothetical knapsack, so the total weight is less than or equal to the required weight. To come to an optimized solution for such a problem, a...Show More

We introduce a hybrid algorithm for the 0–1 multidimensional multi-objective knapsack problem. This algorithm, called GTSMOKP, combines a genetic procedure and a tabu search operator. The algorithm is evaluated on 9 well-known benchmark instances and shows highly competitive results compared with two state-of-the-art algorithms.Show More

Since these biomedical ontologies are mostly developed independently and many of them cover overlapping domains, establishing meaningful links between them, so-called biomedical ontology matching, is critical to ensure inter-operability and has the potential to unlock biomedical knowledge by bridging related data. Due to the complexity of the biomedical ontology matching problem (large-scale optim...Show More
This paper presents a new model to calculate the effort component of a software project. To find the optimal values of the parameters of the proposed model, this study used genetic algorithm (GA), simulated annealing (SA) and tabu search (TS) based algorithms. The results of the heuristic algorithms used are also compared.Show More
A modified tabu search method for global optimizations of inverse problems is presented. In the proposed algorithm, the whole search procedure is divided into three different phases: intensification, diversification, and refinement. Two “new point generating mechanisms” as well as a “dynamic parameters updating” rule are proposed to improve the searching efficiency without compromising the solutio...Show More
The channel assignment problem (CAP) in cellular networks is concerned with the allocation and reuse of the frequency spectrum to the base stations in such a way that both the interference constraints and the traffic requirements of the cells are met. In this paper, we apply a reactive tabu search based method to solve the CAP and compare this approach with the classical tabu search as well as gen...Show More

Unmanned Aerial Vehicles (UAV) are a potential solution to fast and cost efficient package delivery services. There are two types of UAVs, namely fixed wing (UAV-FW) and rotor wing (UAV-RW), which have their own advantages and drawbacks. In this paper we aim at providing different solutions to a collaborating multi-agent scenario combining both UAVs types. We show the problem can be reduced to the...Show More
In the realm of combinatorial optimization, the Tabu Search algorithm has proven to be a powerful tool for solving complex problems.

For increasing the utility rate of the log material, it is very important to obtain the maximum cylinder cut from round logs. The cross-section of a log can be viewed as a quasi-circle.
