Another advantage of free choice (Extended Abstract)
1983
Proceedings of the second annual ACM symposium on Principles of distributed computing - PODC '83
This result shows another advantage of probabilistic protocols, since any deterministic solution to the "Byzantine Generals" problem cannot reach agreement in less than t ~ 1 rounds, (see [1, 2] ). ...
Here, if the number of faulty )rocesses, t, satisfies 5t < N, where N is the ;oral number of the processes, then completely asynchronous agreement is possible (Theorem 2). ...

A simple algorithmically reasoned characterization of wait-free computation (extended abstract)
1997
Proceedings of the sixteenth annual ACM symposium on Principles of distributed computing - PODC '97
This paper introduces two new novel tools for the study of distributed computing and shows their utility by using them to exhibit a simple derivation of the Herlihy and Shavit characterization of wait-free ...
The first tool is the notion of the iterated version of a given model. ...
Thus, since we cannot say that one complete characterization is more complex than another, the way to compare characterizations is qualitative, that is, by the ease with which they allow various interesting ...

Choice coordination with multiple alternatives (preliminary version)
[chapter]
1992
Lecture Notes in Computer Science
The goal is to design a wait-free protocol for n asynchronous processes which causes all correct processes to agree on one out of k possible alternatives. ...
The agreement on a single choice is complicated by the fact that there is no a priori agreement on names for the alternatives. ...
In this abstract we give only a sketch of the proof of Part 1 of Theorem 2. The complete protocol on which the proof is based is given in Figure 2 . ...

What is a 'Good' Encoding of Guarded Choice?
1997
Electronical Notes in Theoretical Computer Science
The -calculus with synchronous output and mixed-guarded choices is strictly more expressive than the -calculus with asynchronous output and no choice. ...
In detail, we present a series of encodings for languages with (1) input-guarded choice, (2) both input-and output-guarded choice, and (3) mixed-guarded choice, and investigate them with respect to compositionality ...
A deadlock-and divergence-free encoding of this triggers the continuation processes in the n=m clause of the receiver's protocol. ...

Then, quickly recalling the uniform encoding of input-guarded choice of [NP96] , we extend it to a uniform encoding of output-guards in the context of separate choices ( §3). ...

A randomized encoding of the π-calculus with mixed choice
2005
Theoretical Computer Science
We consider the problem of encoding the -calculus with mixed choice (i.e. input/output guarded choice) into the asynchronous -calculus. ...
This research has been supported by Projet Rossignol of ACI Sécurité Informatique (Ministère de la recherche et nouvelles technologies). agreement on choices is often difficult to achieve. ...

M-DPOP: Faithful Distributed Implementation of Efficient Social Choice Problems
2008
The Journal of Artificial Intelligence Research
Faithfulness ensures that no agent can benefit by unilaterally deviating from any aspect of the protocol, neither information-revelation, computation, nor communication, and whatever the private information ...
In the efficient social choice problem, the goal is to assign values, subject to side constraints, to a set of variables to maximize the total utility across a population of agents, where each agent has ...
The three anonymous reviewers also provided excellent suggestions for improving the exposition of this work. An earlier version of this paper appeared in the Proc. ...
