Evolved Signals: Expensive Hype vs. Conspiratorial Whispers Artiicial Life Models of Communication
Artiicial life models of the evolution of communication have usually assumed either cooperative or competitive contexts. This paper presents a general model that covers signalling with and without connicts of interest between signallers and receivers. Krebs & Dawkins (1984) argued that a connict of interests will lead to an evolutionary arms race between ma-nipulative signallers and sceptical r...
متن کاملSaturated Neural Adaptive Robust Output Feedback Control of Robot Manipulators:An Experimental Comparative Study
In this study, an observer-based tracking controller is proposed and evaluatedexperimentally to solve the trajectory tracking problem of robotic manipulators with the torque saturationin the presence of model uncertainties and external disturbances. In comparison with the state-of-the-artobserver-based controllers in the literature, this paper introduces a saturated observer-based controllerbas...

This paper presents a general model that covers signalling with and without connicts of interest between signallers and receivers. Krebs and Dawkins (1984) argued that a con-ict of interests will lead to an evolutionary arms race between manipulative signallers and sceptical receivers, resulting in ever more costly signals; whereas common interests will lead to cheap signals or \conspiratorial ...
متن کامل-800-call-me: the Myth of the Passive Prospect 1-800-call-me: the Myth of the Passive Prospect
Models of the evolution of signalling have often failed to consider the role of signal receiver as anything more than that of a passive recipient of signals. This passivity takes three forms. First, receiver's are often modelled as valuing information for its own sake, whereas signallers are taken to place diiering values on receiver response. Second, receivers are often considered to be free f...
متن کاملTri-trophic ecology of native parasitic nest flies of birds in Tobago
Introduced parasites threaten host populations around the world. For example, introduced parasitic nest flies (Philornis downsi) have contributed to the decline of several species of Darwin’s finches in the Gal apagos Islands. Introduced parasites are thought to have severe effects on native hosts because the hosts do not have effective defenses against such parasites and/or because introduced ...
