Researches in the ant colony optimization algorithm has been expanding rapidly both in academia and industry. The correlated courses have been offered at many universities. However, the teaching methods for the algorithm are not sufficient. This paper proposes an experimental tool for the teaching of the ant colony optimization algorithm. The traveling salesman problem is conducted as the application of the tool. In this context, the tool is developed with friendly graphical user interfaces for teaching the algorithms. Graduate students at Nanjing Agricultural University can use this tool to learn the antcolonyalgorithm. Experiments for the optimal design can be conducted by students through the manipulation of the parameters.

An adaptive contract net protocol which can adapt to dynamic environment is proposed based on ant colony optimization algorithm. hi the negotiation process of task allocation, the probability of the contractor being selected is related with the contractor's credibility and ability. Several experiments are performed to show the advantages of this algorithm, it has a better decision quality when task recurrence rate (TRR) unchanged, and the communication traffic (CT) remains at a low level as TRR increases when the number of tasks (NT) unchanged. As a result, the algorithm can enhance the decision quality and reduce the communication traffic.

Home delivery is a new trend in logistics at present. The distribution path planning has a great impact on customer's satisfaction and the total cost of operation in home delivery industry. In This paper, we construct the distribution path planning problems in the industry of logistics and home delivery based on ant colony optimization algorithm, the optimal vehicle's number and the best distribution path can be found in the shortest time by using the model advised in the paper. It is found that there is no obvious correlation between the service and the total costs of delivery after the analysis. So, home delivery companies can select the optimal path planning, i.e. a lower cost of delivery and higher level of service, according to their service policies.

Back propagation algorithm (BP) is widely used as a multilayer feedforward neural network model in the analysis of water engineering projects monitoring data, but it has low solution accuracy, slow search speed and easy to get into a local minimum. To overcome these shortcomings, in this paper, a new learning method of neural network with antcolonyoptimization (ACO) is introduced to achieve optimization solution of the model weights, the ACO-BP monitoring model of dam deformation is established as well. And actual examples show that the antcolonyalgorithm is effective and rapid.

An improved antcolonyalgorithm, differential evolution chaos antcolonyoptimization (DEACO) algorithm, was proposed to plan an optimal collision-free path for mobile robot in 3-D environment. It utilized differential evolution algorithm to update pheromone and chaos disturbance factor was added when pheromone updates for possible stagnation phenomenon. So it enhances escaping capability of algorithm, avoids path-deadlock situations as well as improves the efficiency of planning optimal path. The simulation results indicated that the optimal path on which the robot moves can reach safely and can be rapidly obtained under 3-D space environment, the effect being very satisfactory.

Creative industry clusters are attracting particular interest as a result of the greater economic growth potential. The successful and effective creative industry clusters involve many factors,. of which selection of clusters Partners is a critical issue. In general, the purpose of partner selection for creative industry clusters is to enhance the economical efficiency as much as possible while simultaneously quickly responding to and satisfying practical requirements. So this paper applies ant colony optimization algorithm to select clusters partners for creative industry based on the establishment of the multi-goal decision-making model using 0-1 integer programming. In addition, the paper presents an example to illustrate the validity of the proposed algorithm to select clusters partners for creative industry.

Due to Wireless network delay and large delay time of the controlled plant, the performance of the wireless networked control systems (WNCS) is deteriorates. In order to effectively eliminate the influence of network delay and large delay time, a novel structure of the WNCS is proposed that new Smith predictor combined with neural network prediction and identification model. Nonlinear system's delay time must be well identified. The abrupt mutation result from the training error sum square of the real output and the expected output of the neural network was used to identify the delay time. The input sample period of the neural network was changed so that it could discriminate the delay time of the nonlinear model. The discriminated large time-delay was applied to neural network prediction model. The errors between input and prediction model output were used to search PID controller parameters based on ant colony optimization algorithm. The method was applied to control boiler combustion system. The simulation results show that this scheme has much better advantage of celerity and robustness. This is the paper style requirement for the Chinese Control Conference. The writers of papers should and must provide normalized electronic documents in order for readers to search and read papers conveniently.

It is difficult to have good performance to control large delay time system. A neural network identification method for nonlinear system's delay time was discussed. Using the abrupt mutation resulted from the training error sum square of the real output and the expected output of the network, this method changed the input sample period of the neural network so that it could discriminate the delay time of the nonlinear model. Combining the discrimination of neural network system with long time delay and the control method based on model prediction, searching PID controller parameters based on ant colony optimization algorithm, it was applied to control boiler combustion system. The simulation results show that this scheme has much better advantage of celerity and robustness.

The past two decades have witnessed tremendous research activities in optimization methods for communication networks. One important problem in communication networks is the Weighted Ring Arc-Loading Problem (combinatorial optimization NP-complete problem). This problem arises in engineering and planning of the Resilient Packet Ring (RPR) systems. Specifically, for a given set of non-split and uni-directional point-to-point demands (weights), the objective is to find the routing for each demand (i.e., assignment of the demand to either clockwise or counter-clockwise ring) so that the maximum arc load is minimised. In this paper, we propose a Hybrid ant colony optimization algorithm to solve this problem. We compare our results with the results obtained by the standard Genetic algorithm and Particle Swarm optimization, used in literature.
