Rock Paper Scissors

We recreate real-life biological processes in simulations

Get Started

In ecology, the rock-paper-scissors game is used to model interactions such as predation, resource competition, and symbiosis. This can help to understand how different species or individuals interact and influence each other in an ecosystem. Additionally, the rock-paper-scissors game can be used to explore how evolution can influence the strategies used by species or individuals in competitions.

One interesting aspect of the rock-paper-scissors game in ecology is the concept of coexistence. In many cases, the game can lead to a cyclic dominance between different strategies, where each strategy is temporarily dominant over others, but eventually loses to a third strategy. This cyclic dominance can allow multiple strategies to coexist in an ecosystem, rather than having one dominant strategy that eliminates others.

Another aspect to consider is the influence of external factors on the game, such as the availability of resources or the presence of other species. These external factors can change the outcome of the game, and thus the coexistence probability of different strategies. For example, if one resource becomes scarce, a strategy that is dependent on that resource may become less advantageous, leading to a shift in the dominance of different strategies.

The reasons why we work at the frontier of science


Computational cluster PROTEU/ECT, funded by Fapern/CNPq: 104 processing cores Quad-Core Intel i7 3770 with 800 GB RAM


We build our code in C, Python. Our jobs follow Shell-Script algorithms based on the GSL - GNU Scientific Library


Our conclusions are based on sets of millions of simulations. The statistical analyses are accurate and the outcomes are robust


Our results are presented at the best conferences worldwide. Our papers appear in high-impact factor peer-review journals


We benefit from the cooperation of physicists, biologists, mathematicians and data scientists from major universities


A series of articles published since 2012 guarantees the excellence of the research carried out by our team.
