Abstract
This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a means for determining such a set. We characterize the class of extensional strategies that can be defined intensionally. We also give some hints towards a logical characterization of intensional strategies and propose a few challenging perspectives.

type="abstract" xml:lang="en">This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a means for determining such a set. We characterize the class of extensional strategies that can be defined intensionally. We also give some hints towards a logical characterization of intensional strategies and propose a few challenging perspectives.</div></front></TEI><affiliations><list><country><li>France</li><li>États-Unis</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Nancy</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Bourdier, Tony" sort="Bourdier, Tony" uniqKey="Bourdier T" first="Tony" last="Bourdier">Tony Bourdier</name></region><name sortKey="Cirstea, Horatiu" sort="Cirstea, Horatiu" uniqKey="Cirstea H" first="Horatiu" last="Cirstea">Horatiu Cirstea</name><name sortKey="Kirchner, Helene" sort="Kirchner, Helene" uniqKey="Kirchner H" first="Hélène" last="Kirchner">Hélène Kirchner</name></country><country name="États-Unis"><noRegion><name sortKey="Dougherty, Daniel" sort="Dougherty, Daniel" uniqKey="Dougherty D" first="Daniel" last="Dougherty">Daniel Dougherty</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
