Improved Approval Runoff is a trying to fix Two-round runoff, to avoid cases
like 2002 French presidential election. You can approve your favourite
candidate with low chances of winning, and other satisfactory frontrunner.

In Rio de Janeiro mayor election of this year, for example,the polls
revealed than the 1st candidate was Eduardo Paes, a centrist, and the 2nd
was Marcelo Crivella, a conservative protestant politician. The leftist
votes were splitted between Fernando Gabeira (Green party) and Jandira
Feghali (Communist Party). On the election day, many voters of Feghali
changed their votes for Gabeira, an espontaneous compromise strategy (in
Brazil we call this strategy as "voto útil = useful vote"). The result is
that Paes and Gabeira will contest the runoff.

If Rio election was conducted using Improved Approval Runoff, Feghali`s
supporters were be able to approve both Feghali and Gabeira.
