Abstract:Traditional Genetic Algorithm for solving Job Shop Scheduling Problems has some shortcomings such as slow convergence and easy to bring immature convergence. On the basis of Virus Evolutionary Genetic Algorithm (VEGA) and Genetic Algorithm with Catastrophe factor, an improved Virus Evolutionary Genetic Algorithm with Catastrophe factor (IVEGA-C) was proposed.

The improved algorithm speeded up the convergence rate of the Genetic algorithm, avoided the premature phenomena and to fall into local optimal scheduling solution. The simulation results verify that IVEGA-C on solving the Job Shop Scheduling Problems is better than traditional Genetic Algorithm and VEGA. At last we give an example of using this algorithm to solve scheduling problems in our real-world.

Abstract:For a class of second-order multi-agent systems with a fixed and undirected communication topology and uniform delays systems, linear consensus protocols with time-delayed communications are adopted, the stability conditions are analysised. As the order of system is very high, the stability analysis of the characteristic equation becomes intractable. This paper proposes a new analysis approach via decomposing the characteristic equation of system into a set of factors and using the CTCR method, derives the communication delay of each eigenvalue, and obtains the accurate upper bound of delay of the system. We also explore the stability region generated through the protocol. The results show that in a case of a spanning tree, when time delay is less than the decision value, the stability of the system can be achieved. Finally, numerical simulation shows the effectiveness of the results.

But to the training samples in few or the training samples that are far from the cluster center, the classification results is poor. To solve this problem, this paper proposes a classification model based on the mean update (MU), by expanding the training sample and updating the mean center to improve the classification results of the test data; and on this basis, it proposes the MU-based minimum distance (MU-MD) classification model, and uses the MU's classification results to recalculate the mean of all test samples, then all test samples are re-divided by using the minimum distance method, so as to determine the final category attribution. This can partially correct misclassification in the MU category process and further improve the classification results.
