According to the Barabási-Albert model, the ability of a node to acquire more links grows with the node's age. But in reality newer nodes can acquire a large number of links and become hubs, despite their age. To try and explain this behavior, the Bianconi-Barabási model was created. Choose the incorrect alternative regarding this model.
- A new property of a node is introduced, namely, its fitness, that represents its ability to turn a random link into a permanent link.
- The new model is composed of two main steps. In the first step, a new node is added in the network with a random fitness.
- The new model is composed of two main steps. In the second step, links are created using preferential attachment.
- Preferential attachment in this model is driven by the product of the node's fitness by its degree.
- None of the above.
