Evolution of cooperation in multichannel games on multiplex networks

by Amit Basak, Supratim Sengupta

Humans navigate diverse social relationships and concurrently interact across multiple social contexts. An individual’s behavior in one context can influence behavior in other contexts. Different payoffs associated with interactions in the different domains have motivated recent studies of the evolution of cooperation through the analysis of multichannel games where each individual is simultaneously engaged in multiple repeated games. However, previous investigations... Читать дальше...

Optimisation strategies for directed evolution without sequencing

by Jessica James, Sebastian Towers, Jakob Foerster, Harrison Steel

Directed evolution can enable engineering of biological systems with minimal knowledge of their underlying sequence-to-function relationships. A typical directed evolution process consists of iterative rounds of mutagenesis and selection that are designed to steer changes in a biological system (e.g. a protein) towards some functional goal. Much work has been done, particularly leveraging advancements in machine learning, to optimise the process of directed evolution. Читать дальше...

The representation of abstract goals in working memory is supported by task-congruent neural geometry

by Mengya Zhang, Qing Yu

Successful goal-directed behavior requires the maintenance and implementation of abstract task goals on concrete stimulus information in working memory. Previous working memory research has revealed distributed neural representations of task information across cortex. However, how the distributed task representations emerge and communicate with stimulus-specific information to implement flexible goal-directed computations is still unclear. Here, leveraging electroencephalography... Читать дальше...
