      Achieving reliability in master-worker computing via evolutionary dynamics 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Sánchez, A. (2012)
      This work considers Internet-based task computations in which a master process assigns tasks, over the Internet, to rational workers and collect their responses. The objective is for the master to obtain the correct task ...

      Algorithmic mechanisms for internet supercomputing under unreliable communication 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2011)
      This work, using a game-theoretic approach, considers Internet-based computations, where a master processor assigns, over the Internet, a computational task to a set of untrusted worker processors, and collects their ...

      Algorithmic mechanisms for internet-based master-worker computing with untrusted and selfish workers 

      Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2010)
      We consider Internet-based master-worker computations, where a master processor assigns, across the Internet, a computational task to a set of untrusted worker processors, and collects their responses

      Algorithmic mechanisms for reliable crowdsourcing computation under collusion 

      Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Pareja, D. (2015)
      We consider a computing system where a master processor assigns a task for execution to worker processors that may collude. We model the workers' decision of whether to comply (compute the task) or not (return a bogus ...

      Algorithmic mechanisms for reliable master-worker internet-based computing 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2014)
      We consider Internet-based master-worker computations, where a master processor assigns, across the Internet, a computational task to a set of untrusted worker processors, and collects their responses. Examples of such ...

      Applying the dynamics of evolution to achieve reliability in master-worker computing 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Sánchez, A. (2013)
      We consider Internet-based master-worker task computations, such as SETI@home, where a master process sends tasks, across the Internet, to worker processes

      Crowd Computing as a Cooperation Problem: An Evolutionary Approach 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Sánchez, A. (2013)
      Cooperation is one of the socio-economic issues that has received more attention from the physics community. The problem has been mostly considered by studying games such as the Prisoner's Dilemma or the Public Goods Game. ...

      Designing mechanisms for reliable internet-based computing 

      Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2008)
      In this work, using a game-theoretic approach, cost-sensitive mechanisms that lead to reliable Internet-based computing are designed. In particular, we consider Internet-based master-worker computations, where a master ...

      Internet computing: Using reputation to select workers from a pool 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2016)
      The assignment and execution of tasks over the Internet is an inexpensive solution in contrast with supercomputers. We consider an Internet-based Master-Worker task computing approach, such as SETI@home. A master process ...

      Multi-round Master-Worker Computing: A Repeated Game Approach 

      Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Pareja, D. (IEEE Computer Society, 2016)
      We consider a computing system where a master processor assigns tasks for execution to worker processors through the Internet. We model the workers' decision of whether to comply (compute the task) or not (return a bogus ...

      Reputation-based mechanisms for evolutionary master-worker computing 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Sánchez, A. (2013)
      We consider Internet-based Master-Worker task computing systems, such as SETI@home, where a master sends tasks to potentially unreliable workers, and the workers execute and report back the result. We model such computations ...
