Optimal foraging theory has been criticized for underestimating patch exploitation time. However, proper modeling of costs not only answers these criticisms, but it also explains apparently irrational behaviors like the sunk-cost effect. When a forager is sure to experience high initial costs repeatedly, the forager should devote more time to exploitation than searching in order to minimize the...

Techniques which may reduce the false alarm rate of sliding networks employed in ASR (automatic speech recognition) and OCR (optical character recognition) problems are reviewed. Such techniques include the use of hypersphere classifiers, training out of negatives, addition of garbage units, and exploitation of multiple networks. The combination of several techniques may reduce the false alarm ...

Paradigms of sustainable exploitation focus on population dynamics of prey and yields to humanity but ignore the behavior of humans as predators. We compared patterns of predation by contemporary hunters and fishers with those of other predators that compete over shared prey (terrestrial mammals and marine fishes). Our global survey (2125 estimates of annual finite exploitation rate) revealed t...

In this paper, we build a Closed-Loop Nash Equilibrium of a private property productive asset oligopoly. We compare and contrast private with common property in terms of exploitation rates and social welfare, and provide a comparative dynamic analysis with respect to the number of firms in the industry. Contrary to previous studies on oligopolistic exploitation of productive assets, before expl...

In this paper, we analyze the recurrences from the breakability of the dependence links formed in general multi-statements in a nested loop. The major findings include: (1) A sink variable renaming technique, which can reposition an undesired anti-dependence and/or output-dependence link, is capable of breaking an anti-dependence and/or outputdependence link. (2) For recurrences connected by on...

Many renewable resources are in intergenerational common pools, exploited by one generation after another. In our experiment, the stock available to each generation depends on the extent of exploitation by previous generations and on resource’s growth rate, which is either ‘‘slow’’ or ‘‘fast.’’ Subjects show altruistic restraint in exploitation, but not enough to achieve the social optimum. The...

An evolutionary algorithm is an optimization process comprising two important aspects: exploration discovers potential offspring in new search regions; and exploitation utilizes promising solutions already identified. Intelligent balance between these two aspects may drive the search process towards better fitness results and/or faster convergence rates. Yet, how and when to control the balance...
