This paper develops evolutionary foundations for noncooperative gametheoretic solution concepts. In particular, we envision a game as being repeatedly played by randomly, anonymougly matched members of two populations. Agents initially play arbitrarily chosen pure strategies. As play progresses, a learning process or selection mechanism induces agents to switch from less to more profitable stra...

The primal-dual scheme has been used to provide approximation algorithms for many problems. Goemans and Williamson gave a (2−1/(n−1))-approximation for the Prize-Collecting Steiner Tree Problem that runs in O(n3 logn) time—it applies the primaldual scheme once for each of the n vertices of the graph. We present a primal-dual algorithm that runs in O(n2 logn), as it applies this scheme only once...

An efficient one-pot three-component procedure for the synthesis of new chiral spiro-oxindolopyrrolizidines with highly regio-, diastereo-, and enantioselective from 1,3-dipolar cycloaddition of azomethine ylides and optically pure active cinamoyl oxazolidinone are described. The process occurs at room temperature in aqueous ethanol as green solvent and in the absence of any bidentate chelating...

It is both an opportunity challenge for enterprise compensation management. This paper begins with analysis problems further proposes some innovation strategies value pursuits system will he...

Abstract We report the results of an experimental test whether preaching normative appeal sure-thing principle leads decision-makers to make choices that satisfy it. use Allais-type decision problems observe incentive-compatible 147 subjects, which either violate or adhere Subjects are presented with arguments support counterfactual behaviour and then repeat their decisions. violations robust i...
