The evolution of molecular quasispecies on two diierent complex tness landscapes, the Sherrington Kirkpatrick spin glass and the Graph Bipartitioning landscape, is investigated in dependence on replication delity and population size. Three diierent regimes of replication delity are detected. At high copying delity one obtains a population with high mean tness localized around a time independent...

This paper focuses on the role played by the concept of Common Ground by investigating various roles played by consensus and dissensus in different argumentation theories. A dynamic conception of Common Ground as a second order consensus will be invoked instead of a static definition as starting point, condition or result of an argumentative practice.

Simultaneous tracking and formation control is addressed for a team of autonomous agents that evolve dynamically in a space containing a measurable vector field. Each agent measures the local value of the field along its trajectory and occasionally shares relevant information with other agents, in order to estimate the spatial average obtained from averaging measurements across all agents. Usin...

Consensus methods are recognized as valuable tools for data analysis, especially when some sort of data aggregation is desired. Although consensus methods for sequences play a vital role in molecular biology, researchers pay little heed to the features and limitations of such methods, and so there are risks that criteria for constructing consensus sequences will be misused or misunderstood. To ...
