Empty Alternation
We introduce the notion of empty alternation by investigating alternating automata which are restricted to empty their storage except for a logarithmically space-bounded tape before making an alternating transition. In particular, we consider the cases when the depth of alternation is bounded by a constant or a polylogarithmic function. In this way we get new characterizations of the classes AC...
متن کاملThe Impact of Alternation
Alternating automata have been widely used to model and verify systems that handle data from finite domains, such as communication protocols or hardware. The main advantage of the alternating model of computation is that complementation is possible in linear time, thus allowing to concisely encode trace inclusion problems that occur often in verification. In this paper we consider alternating a...

متن کاملTask alternation cost without task alternation: measuring intentionality.
A behavioral dissociation between intention and action was demonstrated by patient AF who sustained damage to the left-hemisphere including the basal ganglia. The patient was tested in a task switching paradigm involving two choice reaction-time tasks: SIZE (small/large) and SHAPE (circle/square). The last block in each of the two sessions involved only one task. AF switched tasks reasonably we...
متن کاملOrigin of Alternation of Generations
Alternation of generations is a common component of all land plants, vascular and nonvascular; it does not express itself in the same manner in any other organisms. Given the other overwhelming similarities in land plant biochemistry, photosynthetic pigments and tissue organization, it seems that the easiest assumption is that they are derivatives of a common ancestor. The origin of alternation...
