Cooperative co-evolution is often used to solve difficult optimization problems by means of problem decomposition. In order to do so efficiently, one must have a good understanding of co-evolution’s dynamical behavior. To build such understanding, we have constructed a methodology for analyzing co-evolution based on dynamical systems theory. In this paper we show how it can be applied to invest...

In this paper we discuss potential benefits and future directions in virtual reality rehabilitation for co-located motor training in children with developmental movement disorders. We discuss the potential for co-located VR to promote participation using cooperative virtual environments, facilitate social learning, and quantify levels of social interaction. We pay particular attention to the ca...

A number of recent models demonstrate sustained and high levels of cooperation within evolutionary systems supported by the endogenous evolution of social structure. These dynamic social structures co-evolve, under certain conditions, to support a form of group selection in which highly cooperative groups replace less cooperative groups. A necessary condition is that agents are free to move bet...

Multi-UAV cooperative path planning is a key technology to carry out multi-UAV tasks, and its research has important practical significance. A combination of single-UAV paths, so the idea problem decomposition effective deal with planning. With this analysis, algorithm based on co-evolution optimization was proposed in paper. Firstly, by analyzing meaning flight, model given. Secondly, we desig...

A new phase BT -CO on Si(100), not accessible with thermal CO (which leads to the T -CO phase), has been observed using an energetic molecular beam of CO and characterized by first principles quantum chemical methods. The BT phase is composed of bridge sBd and terminal sT d sites; it is driven and stabilized by cooperative electrostatic interactions that result because B sT d binding leads to t...
