abstract = "We investigate the application of a version of Genetic
Programming with grammars, called Grammatical
Evolution, and a multi population competitive
coevolutionary algorithm for anticipating tax evasion
in the domain of U.S. Partnership tax regulations. A
problem in tax auditing is that as soon as an evasion
scheme is detected a new, slightly mutated, variant of
the scheme appears. Multi population competitive
coevolutionary algorithms are disposed to explore
adversarial problems, such as the arms-race between tax
evader and auditor. Furthermore, we use Genetic
Programming and grammars to represent and search the
transactions of tax evaders and tax audit policies.
Grammars are helpful for representing and biasing the
search space. The feasibility of the method is explored
with an example of adversarial coevolution in tax
evasion. We study the dynamics and the solutions of the
competing populations in this scenario, and note that
we are able to replicate some of the expected
behaviour.",
