| - | [[|M. J. North and N. T. Collier and J. R. Vos]] | ||
| - | |||
| - | Many agent-based modeling and simulation researchers and practitioners have | ||
| - | called for varying levels of simulation interoperability ranging from shared | ||
| - | software architectures to common agent communications languages. These calls have | ||
| - | been at least partially answered by several specifications and technologies. In | ||
| - | fact, Tanenbaum [1988] has remarked that the "nice thing about standards is that | ||
| - | there are so many to choose from." Tanenbaum goes on to say that "if you do not | ||
| - | like any of them, you can just wait for next year's model." This article does not | ||
| - | seek to introduce next year's model. Rather, the goal is to contribute to the | ||
| - | larger simulation community the authors' accumulated experiences from developing | ||
| - | several implementations of an agent-based simulation toolkit. As such, this | ||
| - | article focuses on the implementation of simulation architectures rather than | ||
| - | agent communications languages. It is hoped that ongoing architecture standards | ||
| - | efforts will benefit from this new knowledge and use it to produce architecture | ||
| - | standards with increased robustness.// | ||

| - | + | //This paper presents an adaptive tit-for-tat strategy and a study of its | |
| - | + | behavior in spatial IPD games. The adaptive tit-for-tat strategy is shown | |
| - | + | elsewhere to demonstrate high performance in IPD tournaments or individual | |
| + | IPD games with other types of strategies, and obtains higher scores than the | ||
| + | pure tit-for-tat strategy. In spatial IPD games, the strategy exhibits stability and | ||
| + | resistance to perturbations, and those properties are more pronounced in | ||
| + | variations of the spatial game model that induce some degree of “noise” : | ||
| + | probabilistic winning, spatial irregularity and continuous time. The adaptive tit- | ||
| + | for-tat strategy is also compared to pure tit-for-tat and found to be more stable | ||
| + | and predominant in perturbed environments.// | ||
