Jogos Não Cooperativos de Localização de Instalações: uma Resenha Non-Cooperative Facility Location Games: a Survey
The Facility Location problem is a well-know NP-Hard combinatorial optimization problem. It models a diverse set of situations where one aims to provide a set of goods or services via a set of facilities F to a set of clients T , also called terminals. There are opening costs for each facility in F and connection costs for each pair of facility and client, if such facility attends this client. ...
متن کاملStep-by-Step Migrations
This paper considers a dynamic model of industry location in which there is a tension between two forces. First, there is the agglomerating force of preference of intermediate input variety that tends to keep an industry at its original location. Second, other location factors matter and these tend to pull the industry in the direction of a new location. A crucial aspect of the model is that th...
متن کاملGuiding neuronal cell migrations.
Neuronal migration is, along with axon guidance, one of the fundamental mechanisms underlying the wiring of the brain. As other organs, the nervous system has acquired the ability to grow both in size and complexity by using migration as a strategy to position cell types from different origins into specific coordinates, allowing for the generation of brain circuitries. Guidance of migrating neu...
متن کاملMutations or Migrations
We study the ABC model in the cyclic competition (A+B → 2B, B+C → 2C, C+A → 2A) and the neutral drift (A+B → 2B or 2A, B+C → 2C or 2B, C+A → 2A or 2C) versions, with mutations and migrations introduced into the model. When stochastic phenomena are taken into account, there are three distinct regimes in the model. (i) In the “fixation” regime, the first extinction time scales with the system siz...
متن کاملSea Turtle Migrations
Sea turtles are slow-maturing animals that are known to make long transoceanic migrations, even returning back to their natal beaches. However, until very recently, the only knowledge of these journeys was available through the tracking of flipper tags when mature females ventured onto land to nest. Conservation organizations and governments have been monitoring these species for a number of ye...
