One of the major issues in dealing with exceptions in open multi-agent systems (MAS) is lack of uniform representation of exceptions and their shared semantics. In the absence of a uniform framework different business...

In this paper, we show the effectiveness of a GA-based Q-learning method to develop a control table for multiple agents. As a GA-based Q-learning method, we employ a method called "Q-learning with dynamic structuring of exploration space based on genetic algorithm (QDSEGA)". In QDSEGA, Q-table for Q-learning is dynamically restructured by a genetic algorithm. QDSEGA combines Q-learning and genetic algorithm effectively, however, it has just employed simple genetic operations in their QDSEGA. We have proposed a crossover for QDSEGA to accelerate the convergence speed to develop a control table for multi-legged robot. In this paper, we show the effectiveness of the proposed neighboring crossover to develop a compact control table for multiple agents.
This paper proposes a new model of P systems where the rules are activated by the presence/absence of certain objects in the neighboring regions. We obtain the computational completeness considering only two membranes...

This paper presents a fuzzy control system to regulate the traffic flow approaching a single real intersection which consists of multiple lanes with turns, by adjusting time parameters and phases of traffic signals. The lanes are cataloged into several groups controlled by individual traffic lights. These lights are further arranged into several light phases. A fuzzy controller was developed to control the time length of each light phase. Evolutionary algorithms were employed to generate the fuzzy logic rule base, using real statistical traffic data for the intersection. To simulate real car flows, new acceleration and deceleration movement models were developed to ensure safe driving by avoiding possible collision. A new fitness function that comprehensively characterizes car flow delay induced from signals was constructed to evaluate the performance of the fuzzy logic controller. Key performance criteria obtained using the fuzzy logic controller were compared with those obtained by the controller used by the Department of Main Roads, Queensland at the intersection.
Scroll bar is one of the most frequently used components of graphical user interfaces (GUIs). It is generally considered to provide overview + detail functionality. The scale ratio of a scroll bar refers to the rate o...

In this paper, we propose the use of Semantic Web technologies to bridge the gap between authoring systems and authors. The core part of our solution is the ontology-based framework that captures the information about the interaction between learning objects (LOs) and four main roles in the educational process (content author, instructional designer, teacher, and learner), and then according to this information proposes the most relevant learning content to the author. The central part of the framework is the Request- Recommendation ontology that formalizes the author's request along with a set of learning content proposals (recommendation), as a response to that request. Furthermore, we propose the use of a weighting scheme to calculate the weight of the content proposals and thus enable their ranking within the recommendation.
The past 15 years has seen the development of a number of programs which perform tasks in the area of humour, but these have been exploratory research prototypes, usually on a very small scale, and none of them intera...

It is shown that every connected, locally connected graph with the maximum vertex degree Δ (G) = 5 and the minimum vertex degree δ (G) ≥ 3 is fully cycle extendable. For Δ (G) ≤ 4, all connected, locally connecte...
