Abstract
Using an agent-model, we conducted an analysis of a two-party system, in
order to identify a pattern of behavior in the influence exercised by
the number core votes on the proportion of the number of annulled votes, which are cast during an election. In a 2d toroidal grid network, where
each node is connected with its four closest neighbors, we introduce the
concept of an opinion network with uniformly distributed nodes that can
have one of three different states, also known as spin: +1, -1 and 0.
Initially, the states +1 and -1 correspond respectively to active votes
for candidate A and candidate B, with the specific feature that these
are not able to change their state core vote (i.e., that do not change
their political preferences). The rest is established as having a state
of 0, known as undecided voters, who will try to become active votes in
favor of one of the two contending candidates, during the process of
interaction with their four closest neighbors (because of their
influence, in real life these would be interpreted as the voters'
immediate surroundings). The model dynamics tend to a state of
equilibrium, in which there are no more voters changing their opinion
upon interaction with his four closest neighbors. Finally, active voters
who decide become part of the valid vote, while the undecided become
part of the annulled vote.
