Climate. To hedge or not against an uncertain climate future?
I t has been over a decade since Nordhaus (1) published his seminal paper on mitigation policy for climate change. His question was “To slow or not to slow?”; his answer was derived from a traditional costbenefit approach. He found that a tax levied on fossil fuel in proportion to its carbon content, which would climb over time at roughly the rate of interest, maximized global welfare. Although...
متن کاملClosure of Hedge-automata Languages by Hedge Rewriting Closure of Hedge-automata Languages by Hedge Rewriting
We consider rewriting systems for unranked ordered terms, i.e. trees where the number of successors of a node is not determined by its label, and is not a priori bounded. The rewriting systems are defined such that variables in the rewrite rules can be substituted by hedges (sequences of terms) instead of just terms. Consequently, this notion of rewriting subsumes both standard term rewriting a...

متن کاملAdaptive Hedge

In most previous analyses the learning rate was carefully tuned to obtain optimal worst-case performance, leading to suboptimal performance on easy instances, for example when there exists an action that is significantly better than all others. We propose a new...
