    An Investigation About Process Matchmaking Performances of Unstructured and Decentralized Digital Environments
    (Ieee, 2007) Cakir, Bugra; Kilic, Hurevren
    Efficient matchmaking is an important problem in unstructured and decentralized digital environments. We report the results of simulations of these environments and provide measurements of match performance focusing on unstructured and decentralized environments. In the study, different environment models including P2P (Hypergrid, Gnutella with/without ultrapeer); small-world (Watts-Strogatz); heavy-tailed and random versions of Autonomous System Waxman model showing power-law distribution property; random and 2D-Grid are considered. The flooding mechanism enabling process encounters for match purposes is uninformed Breadth-First-Search. Simulations show that the matchmaking performance of random environment outperforms the others for almost all different problems and time-to-live settings. On the other hand, the total cost of small world environment model is the highest for almost all setups.

    An Agent-based Trading Infrastructure for Combinatorial Reverse Auctions
    (Ieee, 2014) Bayindir, Hakan; Kilic, Hurevren; Rehan, Mohammed
    A Combinatorial Reverse Auction Trading Infrastructure - CRATI is designed and implemented as an agent-based system. Two basic building blocks Java Agent Development Framework (JADE) and an Open Source Java Constraint Programming Library (Choco Solver) are used to facilitate agent interactions and an optimization task. For our purpose, it is shown that auction Winner Determination Problem (WDP) can suitably be represented as a weighted set covering problem instance whose solution gives the decided winners of the auction process. In order to realize the system, a variation of Contract Net protocol is designed and implemented to handle auctions that occur in the platform from start to finish.

    Mobile Prisoner's Dilemma Game Played on Diverse Habitats
    (Ieee, 2011) Celebi, Remzi; Kilic, Hurevren
    Promotion of cooperative behavior in Prisoner's Dilemma (PD) game while players that are allowed to move between different gaming environments (i.e. habitats) is investigated. The stochastic mobile model under study is realized over connected habitats that are situated on a two dimensional grid environment. The players appearing in the same habitat are allowed to interact with their immediate neighbors. Mobility of a player is defined as movement from its habitat to another based on both obtained payoff and randomly assigned habitat diversity values. By the end of extensive experimentation, it is concluded that player mobility is an effective factor that contributes to promotion of cooperation in spatial evolutionary games. Also, even for higher values of temptation of PD game, habitat diversity supports and triggers a collective resistance for the emergence and promotion of cooperative system behavior.

    Cooperation Formation and Progression Among Culturally Adaptive Rational Agents in Prisoner's Dilemma Game Environment
    (Ieee, 2024) Efe, Berat; Cerkez, Elif; Kilic, Hurevren
    We investigate whether a persistent and stable cooperative behavior can be observed among particle swarm inspired culturally adaptive and rational players in the context of Prisoner's Dilemma game environment. Our obtained results and discussions point out to the initial value sensitivity of the game set up for cooperation progression as well as soundness of the Prisoner's Dilemma game in the explanation player's behavior.
