Abstract :
There are generally many redundant and irrelevant features in high-dimensional datasets, which leads to the decline of classification performance and the extension of execution time. To tackle this problem, feature selection techniques are used to screen out redundant and irrelevant features. The artificial bee colony (ABC) algorithm is a popular meta-heuristic algorithm with high exploration and low exploitation capacities. To balance between both capacities of the ABC algorithm, a novel ABC framework is proposed in this paper. Specifically, the solutions are first updated by the process of employing bees to retain the original exploration ability, so that the algorithm can explore the solution space extensively. Then, the solutions are modified by the updating mechanism of an algorithm with strong exploitation ability in the onlooker bee phase. Finally, we remove the scout bee phase from the framework, which can not only reduce the exploration ability but also speed up the algorithm. In order to verify our idea, the operators of the grey wolf optimization (GWO) algorithm and whale optimization algorithm (WOA) are introduced into the framework to enhance the exploitation capability of onlooker bees, named BABCGWO and BABCWOA, respectively. It has been found that these two algorithms are superior to four state-of-the-art feature selection algorithms using 12 high-dimensional datasets, in terms of the classification error rate, size of feature subset and execution speed. © 2021 by the authors.

Abstract :
In this article, we have two parts. In the first part, we are concerned with the locally Holder continuity of quasi-minima of the following integral functional integral(Omega) f(x, u, Du)dx, (1) where Omega is an open subset of Euclidean N-space (N >= 3), u : Omega -> R, the Caratheodory function f satisfies the critical Sobolev exponent growth condition vertical bar Du vertical bar(p) - vertical bar u vertical bar(p)* - a(x) <= f(x, u, Du) <= L(vertical bar Du vertical bar(p) + vertical bar u vertical bar(p)* + a(x)), (2) where L >= 1, 1 < p < N, p* = Np/N - p, and a(x) is a nonnegative function that lies in a suitable L-p space. In the second part, we study the locally Holder continuity of omega-minima of (1). Our method is to compare the omega-minima of (1) with the minima of corresponding function determined by its critical Sobolev exponent growth condition. Finally, we obtain the regularity by Ekeland's variational principal.

Abstract :
Alternating-time Temporal Epistemlc Logic (ATEL) which is an important kind of multi-agent cooperation logics only takes knowledge into account, but does not deal with belief of agents. By introducing three kinds of belief operators into ATEL, a new multiagent cooperation logic named ATBKL (Alternating-time Temporal Belief and Knowledge Logic) was developed. A model checking algorithm was proposed. It is proved that the model checking complexity of ATBKL is the same as that of ATEL, i.e., the presented logic is better for further study of multi-agent systems.

Abstract :
Temporal logics are often adopted as basic tools to specifying mental states such as belief and goal of agents. Although there are works on non-monotonic extension of linear temporal logic (LTL) and branching time temporal logic (CTL), the non-monotonic extension of alternating-time temporal logic (ATL) which is an important kind of multi-agent cooperation logics has not been discussed yet in literature. To solve this problem, this paper proposed non-monotonic alternating-time temporal logic with belief and goal, namely N-ATL-BG, to facilitate the non-monotonic reasoning of mental states of agents. The semantic model, syntax and semantics of this new logic are developed. A model checking algorithm which can be finished in polynomial time is proposed for this new logic. Examples are given to show its usage.
