Exploration and mapping are fundamental prerequisites for autonomous robots operating in initially unknown environments. In this paper, we evaluate simple yet efficient frontier-based exploration strategies. Furthermore, we discuss improvements to the classic frontier-based exploration strategy by Yamauchi et al. that further shorten the resulting exploration paths and present results from a co...

Intertemporal choice impacts many important outcomes, such as decisions about health, education, wealth, and the environment. However, the psychological processes underlying decisions involving outcomes at different points in time remain unclear, limiting opportunities to intervene and improve people's patience. This research examines information-search strategies used during intertemporal choi...

The solution of the e-Learning is one of the most discussed priorities of modern universities. The whole problem lies in the global approach of which strategy must use to create e-Learning system. This paper describes an evaluation model for some of the existent methodologies used to create e-Learning system. The evaluation model is based on a comparative analysis: strategies, formation, and em...

In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three di erent colors and forms. The two display-halves are identical except for one object mismatched in either color or form. The subject's task is to nd this mismatch. We illustrate the potential of this paradigm for investigating the underlying com...
