abstract = "Although the problem of partition quality evaluation
is well-known in literature, most of the traditional
approaches involve the application of a model built
upon a theoretical foundation and then applied to real
data. Conversely, this work presents a novel approach:
it extracts a model from a network which partition in
ground-truth communities is known, so that it can be
used in other contexts. The extracted model takes the
form of a validation function, which is a function that
assigns a score to a specific partition of a network:
the closer the partition is to the optimal, the better
the score. In order to obtain a suitable validation
function, we make use of genetic programming, an
application of genetic algorithms where the individuals
of a population are computer programs. In this paper we
present a computationally feasible methodology to set
up the genetic programming run, and show our design
choices for the terminal set, function set, fitness
function and control parameters.",
