Creación y libertad : la cuestión tras la discusión entre Pegis y Lovejoy

A fines de los años 40’, el filósofo norteamericano Arthur Lovejoy y el en ese momento Presidente del Pontifical Institute of Mediaeval Studies, Anton Pegis, sostuvieron una interesante discusión sobre la existencia de libertad o necesidad eficiente en el acto divino de crear conforme a la filosofía de Tomás de Aquino. Lovejoy denunciaba una supuesta incoherencia fundamental en las enseñanzas de Tomás al respecto. Según él, en el concepto tomásico de creación se encuentran implicados al mismo tiempo los conceptos de necesidad agente y libre albedrío aplicados al Creador. Esta supuesta contradicción era para Pegis no sólo falsa sino imposible. Aquí repensaremos dos puntos centrales de dicha discusión: en primer lugar, si, como piensa Lovejoy, para Santo Tomás efectivamente existe una contraposición entre la autosuficiencia de Dios y su capacidad para amar otras cosas distintas de Él. Luego, el significado de la frase: “condice a la bondad divina que también otras cosas participen de la misma". (S.th., I, q.19, a.2).

Distributes award protocol: A cooperation and communication method for robots.

In this Master’s Thesis a new Distributed Award Protocol (DAP) for robot communication and cooperation is presented. Task assignment (contract awarding) is done dynamically with contracts assigned to robots based upon the best bid received. Instead of having a manager and a contractor it is proposed a fully distributed bidding/awarding mechanism without a distinguished master. The best bidding robots are awarded with contract for execution. The contractors make decisions locally. This brings the following benefits: no communication bottleneck, low computational power requirement, increased robustness. DAP can handle multitasking. Tasks can be injected into system during the execution of already allocated tasks. As tasks have priorities, in the next cycle after taking into account actual bid parameters of all robots, tasks can be re-allocated. The aim is to minimize a global cost function which is a compromise between cost of task execution and cost of resources usage. Information about tasks and bid values is spread among robots with the use of a Round Robin Route, which is a novel solution proposed in this work. This method allows also identifying failed robots. Such failed robot is eliminated from the list of awarded robots and its replacement is found so the task is still executed by a team. If the failure of a robot was temporary (e.g. communication noise) and the robot can recover, it can again participate in the next bidding/awarding process. Using a bidding/awarding mechanism allows robots to dynamically relocate among tasks. This is also contributes to system robustness. DAP was evaluated through multiple experiments done in the multi-robot simulation system. Various scenarios were tested to check the idea of the main algorithm. Different failures of robots (communication failures, partial hardware malfunctions) were simulated and observations were made regarding how DAP recovers from them. Also the DAP flexibility to environment changes was watched. The experiments in the simulated environment confirmed the above features of DAP.
