UNICA IRIS Institutional Research Information System
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Cagliari dal mese di luglio 2015.
EnglishWe develop three different algorithms for implementing the Preferential Attachment mechanism, with regards to the Yule process, able to describe how statistical power-law distributions, for various properties of OO software systems and of the internet, are generated. Since modern software systems have reached a huge dimension, counting tens, or hundreds of thousand, of units or modules, the efficiency of algorithms for their simulation is a critical issue. We discuss their efficiency for different parameters value, their scaling with system size, and analyze in which cases one is preferable with respect to the others.

| Abstract: | We develop three different algorithms for implementing the Preferential Attachment mechanism, with regards to the Yule process, able to describe how statistical power-law distributions, for various properties of OO software systems and of the internet, are generated. Since modern software systems have reached a huge dimension, counting tens, or hundreds of thousand, of units or modules, the efficiency of algorithms for their simulation is a critical issue. We discuss their efficiency for different parameters value, their scaling with system size, and analyze in which cases one is preferable with respect to the others. | |
