Robustness of Intermediate Agreements for the Discrete Raiffa Solution

Trockel, Walter - Institut für Mathematische Wirtschaftsforschung, … - 2013

First via a counter example it is shown that the Proposition 3 of Anbarci & Sun (2013) is false. Then a gap and a mistake in their proof are identified. Finally, a modified version of their Proposition 3 is stated and proved.

Variations on the Theme of Scarf's Counter-Example

Kumar, Alok; Shubik, Martin - Santa Fe Institute - 2001

In this paper we study the relationship between the stability of a competitive equilibrium (CE) and the price adjustment mechanism used to attain that equilibrium point. Using two specific examples, a three- commodity exchange economy with a unique competitive equilibrium (Scarf's global...

Fitness Distance Correlation Analysis: An Instructive Counterexample

Altenberg, Lee - Santa Fe Institute - 1997

performance of genetic algorithms for global optimization. Here, a counterexample to Hamming-distance based FDC is examined for … what it reveals about how GAs work. The counterexample is a fitness function that is ``GA-easy'' for global optimization …
